The difference is, black people didn't "identify as white" by fiat and expect everyone to believe they were biologically identical to white people, despite race being far more a social construct than TRAs claim sex is. The mid-20th-century civil rights movement agreed there was a difference between black and non-black people besides the word "black" itself.

Now the Church of Gendered Souls is claiming "trans women are biologically female" and "trans women's biological sex is female" and "a trans woman's penis is a biologically female penis" word-for-word all over Twitter and I have screenshots to prove it.

Not all trannies are predators, but all are impostors, and that's the most polite word I can use without lying.
