If consent is not violated, it's not rape. You can't assume that consent is not established... which is what you're doing. Convincing someone they raped their girlfriend or their boyfriend raped them is pretty reprehensible, but I am aware that it goes on.

I don't actually recommend following the lead of these so called Pick Up Artists... but I don't think they were trying to teach anyone to rape. Apparently we should agree to disagree on that point.
