What do you mean "Frminists need to"? Feminists is not some kind of hive minded species that all act the same.
What about those feminists that do not tear down anything that is beneficial to men? You say things like "feminists do not care about men" - it is the same as saying "blacks are criminals", it is a silly generalization with a wrong implication: that all people of a certain group act the same way.
I get it that you dislike the ways certain feminists act; I dislike them too. The difference is, I do not blame everyone for the words/actions of some. That's basically all there is to it.
