I'm in America, and I've certainly never had a conversation where this level of sexism was mentioned. The worst I've heard is a creepy coworker who likes to give back rubs. For all the reasons in the article, I think it's something which is not discussed as much as it should be. All I can say, is anyone who does this stuff should not be employed anywhere.
I've heard a girl talk about her rape in a friendly environment where we were all good friends, it became awkward and impossible to go on. If I was in her shoes I would never bring it up again, so the chances of hearing stuff like these is slim.
Yeah I don't generally talk about this because it brings conversations to a screaming halt, and you have to spend all your time comforting whoever you just told.
