Radical feminists and mens rights advocates don't even define happiness that differently - they just want it for different gender. (I know there are also feminins and mens rights advocates who deal with actual issues of the respective gender and don't bother with philosophy around happiness. Respect to them.)
Excuse me, but you didn't say "radical feminist" before, you said "feminists". And you aren't describing the views of any feminists or radical feminists that I know.
