Bit of a more ventish one, warning for exclusionist and transphobic rhetoric that I don't actually believe of course, but I'm saying anyway as a way to represent what exclus believe.
Contradictory label culture, at least for most labels, is people deciding which of your identities you are based on how they want to invalidate you. I myself can either be trans with internalized transphobia for being genderqueer and cis, or I can just be a cis girl who has no right to be talking over "actual" nonbinary people. I can be a lesbophobic bi person trying to take away lesbian's identity and force them to like men or I can be a biphobic lesbian trying to appropriate bisexuality and exclude nonbinary people from lesbianism. Trans man lesboys can either be creepy guys trying to prey on lesbians or they can be confused butches who fell for transgender ideology. Cistrans people can either also be trans with internalized transphobia like I supposedly am, or they can be cis invaders who aren't trans enough. Mspec straights can be straight people invading the community, or they can be bi people with internalized biphobia. AMAB transmascs and AFAB transfems can either be cis people trying to be special, or (exclusively in the case of intersex afab transfems and amab transmascs) "not count" as AMAB/AFAB because they're intersex (and perisex people took AGAB language wildly out of the intersex context it was coined in.)
That last one is BAD like I know each one are bad in their own way but that last one...ughh... Bluntly being an asshole to intersex people with that.
I can't imagine hearing someone tell me their label(s) and then saying "hmm ...but you're not actually that, you're ____ ___ and if you don't apologize and identify as what I just told you, you're a danger to the LGBTQ community and a faker, a transtrender, trying to be a quirky cishet, and you're identifying yourself the "wrong way""
Like I couldn't imagine myself doing that because guess what?? No one has to prove their identity to me! I just say "ok, cool." And move on!
When people start to unironically say "transtrender" or anything about someone who identifies as queer ACTUALLY being a cishet that's trying to be quirky, invalidating themselves, being a danger to the community, being a predator for identifying a specific way, "you're making the community look bad" blah blah you know the stuff they say. Their point just gets thrown out the window because I am NOT listening to someone who says that!
