Here's the full quote I assume you are referring to -
“You are fucking blackface actors. You aren’t women. You’re men who get sexual kicks from being treated like women. fuck you and your dirty fucking perversions. our oppression isn’t a fetish you pathetic, sick, fuck.”
Quite obviously she is referring to AGP there. Which is a paraphillia. And women don't particularly like their oppression used as a sexual fetish. Some examples of how those who have AGP view women - “an open mouth, an expectant asshole, blank, blank eyes” (Andrea Long Chu) or “sometimes I wonder if dressing up like this is the equivalent of having sex with myself' (Caitlyn Jenner).
(As that term used to be banned here, I have to see how long this stays up). TRA's don't like it when it is pointed out that for at least some (certainly not all) it is a sexual fetish.
I addressed the black face issue in my previous post. Perhaps you missed it?
