Marmalade can I ask why? Not trying to be twatty, I'm genuinely curious!
Read the news?
Men are disproportionately violent against women, children and other men, and enough men think that men should be allowed to be violent against women that it took the feminist movement to actually make male violence against women illegal.
Most men also use pornography and see nothing wrong with the violence against women that is the porn industry, and the fact that they are likely to watch (and wank to) a filmed rape when watching porn.
I understand any woman who sees no reason to give individual men the benefit of the doubt any longer.
I think feminists are divided on whether men have more of an inherent tendency to sociopathy than women or whether gender is nothing but a social construct. If you go with the former then it is logical to feel an aversion to men per se, while the latter implies the problem is patriarchal ideology rather than biological maleness.
Nope. All feminists know that gender is a social construct created to oppress women. (I know, there are so-called feminists who claim that gender is a spectrum and all nice and glittery and snow-flakey, but they don't count)
Some (most) feminists believe that men, as a group, can change and become decent people, some believe that the male sex (not gender) has an inherent tendency towards sociopathy, and that society must evolve to enable women to stay the hell away from violent males.
And most antifeminists also believe that men cannot change, and those people believe that men therefore should not have to change and women should submit to male violence.
While the feminists who believe that men are inherently violent could be said to hate men, the same is true for antifeminists, who are a much larger group.
