This tactic is used to great effect by SJW's. I only need look down the thread to see how much you caused.
Many a times, this type of harassment is mainly what women claim against men. But what exactly is harassment? Well, there's no real good definition. There's a point where any sane individual would agree... But I've also met people that simply asking to go on a date was "harassment". I've also seen cases of obvious sexual harassment (me, when I was sexually harassed by a manager, and then they were subsequently fired). And then I've also witnessed claims of it that one party blew out of proportion.
Except, because someone says " girls", you jump all over that and derail the underlying ideas of harassment and how to develop ideas of what it actually is, and not gut feelings.
