Like, just the fact that some so-called “allies” can point at a vile, horrible trans person and say someone is unworthy of proper pronouns is a blatantly clear sign that cissexism and transphobia are deeply ingrained into them, because cis people aren’t stripped of their validity and their gender when people are angry at them. They aren’t violently assigned another gender on instinct when they do/say something horrendous. Called a terrible member of their gender, maybe have a bunch of negative adjectives or slurs tossed at them, but never inherently have their personhood so violently denied and overwritten like trans people always do when it’s our turn on the stocks.
Anyone who is willing to reject the validity of one trans person because they’re terrible, is someone who never saw trans people as inherently valid as cis people to begin with. Our validity, our authenticity, is not conditional. It is not something we earn, or something that can be revoked. A hypothetical trans woman neonazi would be no less female than your fav cis woman celeb.
If you hate a trans person, express that hate in ways that target why they’re terrible people. When you treat our validity as conditional, all you show is that you hate trans people just as much as those who want to eliminate us from existence, since you clearly don’t think we’re real enough to have our existence respected as truth.
