Listen to yourself. You think that hatred towards a particular demographic is justified. En masse.

You sound like an extremist.

You want to hate millions of men, who you don't know, and who you've never met, simply because of their sex. That's mental.

By justifying misandry, you weaken the entire feminist cause. Why should I support a group of people who hate me for things that I've never actually done as an individual.

Other people, who I've never met, have done bad things and now I'm personally responsible for what they've done because I happen to have the same genitalia as them? What?

You're supposed to treat people as individuals. Not as a part of their group. So no, black people shouldn't walk around hating white people who they've never met or spoken to. People are individuals and are not responsible for the actions of others who happen to be in same demographic as them.
