Have to say, I know a lot of feminists, and I've yet to meet these man-haters in real life. The only places I hear about them tend to be in MRA conspiracy theories up there with chemtrails and HAARP, or occasionally on web forums. I guess statistically speaking, chances are there are women out there who are man haters...but I sure haven't met them.
For example when discussing the importance of consent regarding my, er our, fetish, the only people I've met so far who get it are queer/kink aware feminists.
