I know it's more nuanced than this but I think having a hard policy of thinking anyone who genuinely hates one group of queer people for their identity might as well hate all of us and thus I should block any queerphobic queer person I see can do a lot to save you from believing anything exclusionists say.
"bomb that kills all-" "I just don't get bi women bringing their-" "pansexuality isn't a real thing-" "all lesbians-" "trans men really are the men of the-" "theyfabs-" "pfft aroace people are cringe-" "nonbinary people are actually all-" Instant block. Goodbye. Not listening. It's for both solidarity with your fellow queers AND to protect yourself, because once a person is convinced to hate one group for their immutable traits they can be convinced fairly easily to hate another too, and thus I do not trust them.
Just block these people the second they pop up, they aren't your allies and nothing they have to say is worth listening to.
These types will often try to guilt you into defaulting to their judgement by citing their own identities but that's bullshit. You can, should, and must completely ignore them. A bigot is a bigot, and if you wouldn't listen to a cishetperisex one then you shouldn't listen to a queer one either.
