When I close the browser tab with neoreaction, I have a decent chance of never meeting a neoreactionary in my real life, so the problem is solved. Unfortunately, I cannot say the same thing about Tumblr!feminists. They are also rare, but I have already had the "pleasure" of meeting three of them. (Twice, they have cost me a female friend, because they were a friend of the friend, and have successfully convinced my friend that I am an evil person, because I happen to have an Y chromosome, which is a huge red flag for them. The third time, they have publicly accused my friend of being racist, when she dared to say that some traits correlate with certain genes, in a group of people who previously said more or less that genetics is a burgeoise pseudoscience.)

Unlike neoreaction, feminism happens to be a topic in real life (one could even call it a billion dollar industry, if we include all the government money spent on gender studies, female-only projects, etc.), so its perversions have a real impact. Many people spend a lot of time online, and if they meet the Tumblr version first, some of them will conclude this is the true version.
