TERFism restricts feminism to a tightly defined and controlled ingroup. The criteria for determining who is a real woman, when employed by bigots, will inevitably come to describe the socially dominant form of femininity, which is white femininity. Black and Arab women like Khelif will always fail to pass the standards of white femininity, because they’re not white. The standards are racist. And TERFs invariably pick racist standards, because the kind of people who feel the need to police womanhood to appeal to an imagined ideal are people who will end up doing that in more ways than one. And also, TERFs are always hanging out and allying with overly white supremacist groups, because Nazis are the only people who will put up with assholes like Rowling. That’s why she’s always taking photos with fascists.
