There's a reason there's other letters besides 'G', and "a minority can be hostile to another minority" isn't a new idea.
Of course a person gets booted for attacking other members of the community regardless of who they are.

Same with being pro-LGBT: The activists aren't pro gay people, or pro black, or pro transpeople. They don't want me listening to Douglas Murray, or Gays Against Groomers, or Thomas Sowell. They definitely aren't pro Scott Newgent of "What is a woman?" fame. They're pro rainbow ideologue people. The politics is the point, the minority status simply a convenient shield from criticism and hate claims a cudgel to beat people over the head with.
I think you're committing the error of treating social categories as set-theoretic absolutes when humans are far more multidimensional.
It's like "Well they're not really patriots; they tell me Americans are great but they don't want me talking to Benedict Arnold or Aaron Burr." No, they don't, because those Americans were traitors who hurt their fellow countrymen. "Listen to more LGBTQ voices" and "Don't listen to Gays Against Groomers" aren't actually contradictory concepts; 'listen to' doesn't mean 'give equal, uncritical weight to every'.
The missing sociological tool you may want to dive in on is 'Intersectionality,' which is the concept of how one's privilege is contextual and multidimensional factor; a person can be both oppressed and oppressor.
