When have I ever given you the impression I'm female?
And I'm sorry, but that is too convenient an excuse: if it disgusts you really but you feel like there's no point reacting until we go back in time and kick up a fuss about it to JFK, then you're really saying that we should just allow it all round. The dude got shot in the head. What are you expecting, honestly? The most we can do about it now is to reassess his place in history. And mostly, that's what people have done. What, do you want to put a press conference at his grave stone?
Unless you're intentionally trying to pick the side that's convenient to you, there's really two options: a world where everyone gets to talk like that and keep their jobs, or a world where nobody does.
And I've got little sympathy. Can you imagine the trouble I'd be in if anyone at school even suggested that there's a record of me bantering about women like that? In the position of extreme trust that I'm in? There's no way - my life would just be over at that point, forever. And rightly so. I don't care if you're President or dog catcher: a conversation like that, even a private one, is indicative of appalling character, judgement, and taste of humor.
