I understand what you're saying, Pete, but to be fair, LongHairGal may live in the U.S. where the unwelcomeness of the conduct is actually one of the three elements that determine hostile work environment. (The other two being the severity and the repetition of the conduct.)
The moral of the story is to always treat everyone professionally, but yes, the unprofessional conduct of an unattractive man (or woman) is more likely to be unwelcome, human nature being what it is.
SH is a civil, not a criminal matter so it is not governed by an objective standard, like assault, for example. (Again, in the U.S.)
