   usually under the broad umbrella feminist theory. Men's
   rights/women's rights/human rights are generally all under
   feminist studies because, well, simply, not everybody thinks in
   terms of [x] rights vs [y] power group In short, that's why
   men's rights and women's rights movements look identical from
   the outside. They're on the same spectrum, part of the same
   family / way of thinking.
