"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?
That's none of your business. How people "describe" sexual harassment in casual conversation, is not how sexual harassment is judged against policies, rules, and in common-sense consideration when evaluating punishment for making choices that violated another person's boundaries.
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.
What is the definition of sexual harassment in place in this context? Is it explicitly written and, if it is, how much is left to individual discretion? That is one example of what is mysterious here.
