No one thinks that it does, in fact "sexual harassment" hadn't even crossed my mind. But based purely on what the author wrote (which seems comprehensive, complete with emails), I don't see harassment.
I'm saying the article has no example of actual harassment. There was no name calling, no threats, and no abusive behavior. All I see is a potentially socially-inept guy trying to communicate, and someone reading way too much into his emails (she kept claiming the "threats were insinuated," really?).
