An exclusionist, commonly shortened to exclus, is a discourse term to refer to a person who believes the core purpose of the LGBT+ community is group protection. They tend to care more about historical sources or definitions over personal feelings. They believe that cishet approval is needed in order for lgbt individuals to have rights. Since they prioritize history, they can sometimes dismiss people's feelings, and even boss people around (e.g; "you can't identify as pansexual, it's biphobic). However, not all exclus are guilty of doing this.

Common exclusionist beliefs are (Note: People don't have to inherently have every of these views to be an exclusionist):
-the acronym is LGBT, or sometimes LGBT+
-ace and aro aren't inherently LGBT, they would need to either have same gender attraction, or be trans
-asexuality and aromanticism are not spectrums ("either you're ace or you're not")
-lesbians need to be women, and gays need to be men. Non-binary people are feminamoric or viramoric
-"gay" is a term that's only meant for men who only like men, lesbians and bisexuals should not use the term to refer to themselves
-Mspec identities like pan, omnisexual, or polysexual are not valid, and contribute to biphobia
-some form of gender dysphoria is needed in order to be transgender
-pronouns = gender
-either no neopronouns are valid, or only traditional neos like xe/xem are valid
-Queer is a slur, and shouldn't be used as a term for anyone to use to refer to the community

Someone in the LGBT+ community who thinks that someone else's identity is their business

A person who thinks certain sexual orientation minorities aren't real or valid enough to be a part of the LGBT+ community for various and dubious reasons, as for example not being hated and discriminated enough or invalidating their sexuality in general. Favorite targets are asexuals, pansexuals, bisexuals... And their favorite way of fighting is by delivering a lot of said "nonexistent" hate.

an exclusionist is someone who gatekeeps (excludes) specific sexualities and pronouns from the LGBTQ+ community. most of them excuse sexualities that may be harming others (pansexuality vs bisexuality discourse). exclusionist, unlike inclusionist, can have different beliefs about different sexuality, as one person might not support neopronouns while an other does or some might support the aro/ace spectrum (most do) while others don't. they're the contrast to inclusionist who accept every nounselfs, xenogender, neogender and sexuality despite whether its harmful or not.

another way of saying sexy smart bitches. exclusionists are people who hold exclusionary beliefs about the lgbt community, including, but not limited to, fighting against lesbian, gay, and bisexual erasure, supporting the medicalization of trans healthcare, and sticking by lgbt history.

the term originated from ace discourse on whether or not aces and aros were lgbt, but is now much broader. an exclusionist may even believe aces/aros *are* lgbt; if the rest of their beliefs are exclusionist beliefs, they are a neutralist with an extremely heavy exclus lean, and may choose to say they're exclus for convenience.

contrary to popular belief, not all exclus hate people who disagree with them. many exclus are friends with neutralists, inclus, other exclus, and anyone in-between, as long as both parties agree to disagree. the majority of them follow the classic "hate the sin, not the sinner," rhetoric, with "sins" being problematic lgbt identities.

An exclusionist is a person who gatekeeps (i.e. excludes) certain people or identities from a group. This is particularly prevalent in the LGBTQ+ community, but also occurs in other (usually minority) groups as well. Often times exclusionists stubbornly maintain one viewpoint without attempting to understand those they exclude, even after having their mindsets thoroughly debunked by inclusionists. Exclusionists often treat identities as "clubs" and "in-groups" that they exclude others from in order to feel more valid in their own identities, usually not realizing that those outside the group often do not understand the differences and subject all identities to judgement and oppression.

A lifestyle of exclusion. Someone who is exclusionist is vegan, straightedge, and celibate, among others.

Someone part of the lgbtq+ community who doesn't think being asexual makes you inherently queer. This argument is obviously flawed because lack of sexual attraction makes you not heterosexual therefore you aren't straight being something else then straight you are queer. some Ace Exclusionists don't think asexuals are persecuted enough so they take matters into their own hands.

Loudmouthed children on the internet crying about issues that don't matter at all. They have no bearing in the real world and they are rejected by the majority of their community. Somehow, they manage to twist their own perceptions so that they believe that they are the immortal guardians of the future gay and trans people, instead of whiny brats who don't know what they're talking about and really need to go outside.
