We don't have to prove common knowledge when you can't prove you didn't rape anyone or anything.For all of you who insist that there are only two sexes and gender is the same as sex: PROVE IT WITH A PEER REVIEWED PAPER PUBLISHED AFTER 2015.
Otherwise, put a sock in it and take a seat. Continue to harangue transgender people if you like, but don't fucking start sniveling about how mean they are back at you, you sexist sado-masochistic sycophants.
