You all have this story completely turned around. The alert stalking is against the feminists, not by them. Juries are clearly anti-HOF and will hide posts just because they don't like the poster, and allow nasty attacks if they don't like the person the attack is directed against. One person who addressed sexism found himself the target of five hides in a single day (God knows how many alerts it took to carry that off). Not content with the fact he was flagged, the anti-feminists kept up until he had the five hides required to be gone from the site for three months.
As for women being nasty to women, that too is a result of sexism. The fact is women are raised in this culture to revere men and see other women as competition. That kind of sexism has to be consciously combated in oneself. Some women internalize that misogyny more than others, and as a result they can be vicious against other women. Everyone has met someone like that. They have no or few female friends, much prefer the company of men, judge other women on sexist societal standards about physical attractiveness and body image. My view is that it's not possible for them to hate other women without also hating themselves. By the way, this is something that pervades political party and ideology. One sees it among liberals, moderates, and conservatives.
