"sexual harassment" is a very broad and subjective term. I've heard people describe walking into the same room as "sexual harassment" - extreme example, but it makes the point. What's mysterious is: what did he actually do?
Frankly: if the dynamic between two individuals is as such, that for one to walk into a room has been plainly stated to violate the imposed boundaries of another, THAT is harassment. Textbook. Harassment. That's what restraining orders are for.
I didn't say there was no reason a man should go into a ladies room. I said that it's easy to imagine a situation in which a man entering a ladies room would very definitely be sexual harassment. Like, you know, chasing after a specific woman.
