I don't think all or nothing attitudes fix anything and I think a majority of these people can be made to come around to the reality of the situation. In my opinion when you throw people out, you lock people into their form of thinking.
This isn't about all or nothing, these people are literally not feminists. Please read the article, and understand that these women are actively campaigning to remove rights from other women. They're not allies to women in any way when they're going about that.
And please do not pull that "If you call them TERFs and say they aren't feminists, its your fault that they're still that way" It is not our job to educate the hateful, and its not our fault if they remain hateful. I have no problem trying to teach and help people understand trans issues, but not letting us call a spade a spade is a little ridiculous.
