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.
Ace 1: Damn I'm really sad today I got harassed by an ace exclusionist online.
ace 2: Ignore them you are valid!

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.
"Yeah, we had an Ace Exclusionist try to join our Pride group last week, kicked that kid to the curb"
