The root of “weird” is fate, destiny, witchcraft, the supernatural or unearthly or magical—think of the “weird sisters” who foretell Macbeth’s undoing, or the Greek Fates. The “weird” are usually feminine. To twist the word around and use it to refer to behavior and speech that is explicitly misogynist strikes me as like stabbing someone with the hilt of a knife—it’s your hand that bleeds.
