and I quote
Once again for the people who didn’t get the memo all the other times:
Mansplaining doesn’t simply mean “a man condescended to a woman”. It means “a man with lesser expertise attempted to override a woman with greater expertise AND SUCCEEDED because of societal support for misogyny.” [ADDENDUM: “…even if the woman managed to wrest conversation back from the mansplainer.”]
(My irritated thanks to people who necessitate my revising and revising and revising definitions so that the points are as pointy and clear as possible.)
