Every generation of soft social "scientists" (I use scare quotes because they don't usually use the scientific method. When I say "soft" social scientists I mean e.g. Gender studies people as opposed to demographers.) tends to disagree with the previous generation on huge fundamental tenets for mostly arbitrary reasons. It is wise to take any dictionary-defying claims from these fields with a large grain of salt, because there's a substantial chance that such a claim is made for social or political (but not scientific) reasons.
