> sexismlessness
If you promote reason and common sense, you (are working in order to) get rid off all these problems plus many more. I'm emotionally refreshed to read the post you reply to, and the OP's writing. More sexism doesn't help in trying to remove sexism, and revenge and positive discrimination bring lots of tension among the sides.
I'll add that the best way to oppose something is to promote its opposite. Only because "opposing" has a tendency to backfire. We should therefore promote, for example, sexismlessness. Yes I made up a word.
