This is all very depressing. One is told that progress is a linear thing, and the intuitive assumption would be that the ideas of liberal feminism become universally accepted and the ideas once considered radical feminist would be considered just normal feminism.
But it seems the opposite happened; mainstream got awarded the title of liberal feminism, and what would once have been ordinary feminism is now called "radical".
As for SWERF, it makes as much sense as saying that people trying to get safety precautions put in place for African mineworkers are doing so because they must hate the mineworkers.
Quite. The attempts to convince workers that unions are against their best interests were never as successful, though.
There is another element of absurdity to it - it quite obviously came after TERF and was modelled after that.
No woman ever excluded "Sex workers" from feminism. There are no "sex workers are not allowed here" signs on the doors of feminist clubs, or something. (While, yes, trans are indeed excluded from women-only things, because those are women-only)
I think this shows quite obviously that those words were invented by men.
If women want to accuse others of doing nasty things ... well, I can imagine a lot worse things than being excluded from something I do not at all need for survival.
But men apparently can't. To men, being excluded from women's spaces is the worst thing that ever happened to them. (Well, white men, though I suppose for MoC, excluding them is also the worst thing that women ever did to them.)
