It reminds me of the "allies" who insist that in LGBTQIA+ the A stands for ally instead of asexual. Literally replacing a marginalized sexual identity community with being tangential to the larger community.

Oh my god, they are the worst. Sometimes they're just clueless and will happily listen when you correct them, but I've found a lot of them will fight back and try to gatekeep. Because someone who is cishet deserves to be considered part of the community more than someone who doesn't experience sexual attraction (asexual), romantic attraction (aromantic) and/or the concept of gender (agender). Because someone who is cishet should be deciding who is allowed in a movement based around civil rights for people who aren't cishet.

If you don't think it's appropriate for white people to tell black people how to run their civil rights movements or how to run a tribe as an honorary tribal member, why would it be appropriate for a cishet to tell queer people how to run their movement? If you're an ally then you're here to listen and amplify our voices, not tell us how to be gay (and you sure as hell shouldn't be policing our voices and tell us what is or isn't queerphobic *looks at the painfully obviously straight tankies who crawled up my asshole and told me I was homophobic because I told them to stop sucking Kim Jong Un's dick*)
