LGBTQphobia
1 — the group in question

People who are lesbian, gay, bisexual, trans, queer, or perceived as such.

2 — -phobia, from the Greek phóbos

"Fear." Here, an irrational fear that turns into rejection, violence, or discrimination.

Nomenclature is an independent dictionary that defines, term by term, the different forms of LGBTQ+ phobia – and puts their origins and real-world effects into context. This project has no affiliation with any organization or campaign mentioned on this site; every reference below is factual and third-person.

We built this as a dictionary rather than a magazine because the vocabulary itself is part of the problem: many people confuse homophobia, biphobia, transphobia, and a handful of less familiar terms, which makes it harder to talk clearly about any of them. A shared, precise vocabulary is a small but real tool against confusion.

About This Dictionary

Why an independent dictionary, and not a campaign site

Most of what exists online about LGBTQ+ phobia comes from one of two places: advocacy campaigns built around a specific date or petition, or academic papers written for specialists. Both are valuable, but neither is quite what a parent, teacher, journalist, or curious reader usually needs when they come across an unfamiliar term and want a clear, short, trustworthy definition.

Nomenclature tries to fill that specific gap. Each entry in the glossary below is written independently, in plain language, and cross-checked against multiple public sources rather than a single one. Where a statistic is used, we mark it clearly and point to where it should be verified – we would rather flag a gap than quietly overstate our certainty.

We are not a government body, a helpline, or a substitute for legal or medical advice. We are also not affiliated with any of the organizations referenced later on this page – they are cited the way a bibliography cites a source, not the way a press release speaks on someone's behalf.

Glossary

Eleven entries, one underlying pattern

Alphabetical order

Each of the terms below describes a distinct target and a distinct social dynamic, even though they share the same underlying mechanism: an irrational fear of a group, translated into rejection, mockery, or exclusion. Reading them side by side makes the pattern easier to spot – and easier to name when you see it.

A
Acephobia n.

Rejection of, or discomfort with, asexual people – those who experience little or no sexual attraction. Acephobia often shows up as disbelief ("that's not a real orientation") or as pressure to "fix" what is treated, wrongly, as a deficiency rather than a variation.

A
Arophobia n.

Rejection of aromantic people, who experience little or no romantic attraction. It is frequently confused – incorrectly – with an inability to love or to form close relationships of any kind.

B
Biphobia n.

The erasure or questioning of attraction to more than one gender. Biphobia is somewhat unusual in that it can come from both heterosexual and LGBTQ+ communities, each sometimes dismissing bisexuality as "just a phase" or "not a real identity."

E
Enbyphobia n.

Rejection of non-binary people, whose gender identity does not fit exclusively into "man" or "woman." It often takes the form of refusing to use a person's stated name or pronouns.

G
Gayphobia n.

A form of homophobia that specifically targets gay men, frequently tied to rigid ideas about masculinity that are perceived as being under threat.

H
Homophobia n.

The general term for rejection or hostility toward people attracted to others of the same gender. Historically the first of these terms to enter wide public use, before the more specific vocabulary below developed alongside it.

I
Interphobia n.

Rejection or medicalization of intersex people, who are born with physical sex characteristics that don't fit typical binary definitions of male or female bodies. Interphobia often shows up as unnecessary or non-consensual medical intervention.

L
Lesbophobia n.

A form of homophobia targeting women attracted to other women, frequently combined with sexism – which is what analytically separates it from gayphobia rather than making it simply a subset of it.

P
Polyphobia n.

Rejection of people in consensual non-monogamous relationships, sometimes wrongly equated with generalized infidelity or a lack of commitment.

S
Serophobia n.

Discrimination against people living with HIV, regardless of actual transmission risk – frequently driven by outdated understanding of modern treatment, which can reduce transmission risk to effectively zero.

T
Transphobia n.

Rejection of people whose gender identity differs from the sex they were assigned at birth. One of the most extensively documented forms of LGBTQ+ phobia at the legal and policy level, in both directions – protection and restriction.

A Numbers-Based Reference

A risk map, in three shades

Legal status varies enormously by country – from full legal protection to active criminalization. The three categories below are a simplified starting point, not a precise legal reference; always check a current, dedicated source (such as ILGA World's annual mapping) before relying on a specific country's status.

Protected zone
~30

Countries that have legalized marriage between people of the same gender.

source to add
Grey zone
≥ 60

Countries with no explicit legal protection, but no formal criminalization either.

source to add
High-risk zone
70+

Countries where same-gender relationships or trans identities remain criminalized.

Legal status is not static: several of these categories have shifted within the last decade.
Essay

Where these fears come from, and what they produce

LGBTQ+ phobia almost never rests on a demonstrated threat. It tends to take root in inherited narratives – religious, cultural, or familial – that frame sexual and gender diversity as an anomaly to be corrected rather than an ordinary part of human variation. Understanding those narratives doesn't excuse their effects, but it does explain why the fear persists even where no real danger exists.

Three ways the fear shows up

That underlying narrative plays out in a few recognizable ways. It first fuels preventive censorship: removing books, banning certain educational materials, or blocking any mention of LGBTQ+ people around children, all in the name of a supposed protection. It also feeds sexualized stereotyping, which reduces entire identities to assumed behavior, in turn "justifying," in the eyes of those who hold the stereotype, distrust or hostility. And it can lead to outright pathologization: the idea that these identities are an illness or a choice to be "corrected," a line of reasoning that has historically been used to justify what are now recognized as conversion therapy practices.

Measurable effects, even when the fear itself is irrational

The fact that a fear is irrational doesn't make its consequences any less real. Several public health studies associate a hostile social climate with higher rates of psychological distress, avoidance of medical care, and family estrangement among LGBTQ+ people. These effects are not limited to countries where the law criminalizes – social exclusion doesn't stop at a border, and it can be just as damaging in a country with strong legal protections but a hostile local community.

Media representation matters more than it might seem

How LGBTQ+ people are portrayed in film, television, and news coverage shapes public perception long before most people ever meet someone who challenges their assumptions directly. Flattened or exaggerated portrayals reinforce stereotypes; accurate, varied portrayals tend to reduce them over time. This is one reason media literacy is often mentioned alongside legal reform as a long-term lever for change.

What "being an ally" actually involves

Part of the response to these fears comes from people who are not themselves part of LGBTQ+ communities but choose to publicly support them. This role, often called an "ally," has had its own flag for several years, distinct from the flags specific to each identity. In practice, allyship tends to look less like grand gestures and more like small, consistent choices: using someone's correct name and pronouns, not laughing along with a joke that targets someone's identity, or simply not assuming everyone in a room is heterosexual or cisgender by default.

A brief history of May 17

The international day observed on May 17 dates back to 2004. It was originally centered on homophobia alone, marking the anniversary of the World Health Organization's 1990 decision to remove homosexuality from its classification of mental disorders. Over the following two decades, the day's scope broadened to explicitly include transphobia, and later biphobia, reflecting a wider public understanding of how many distinct forms this phenomenon actually takes.
