I don't mean this in any way to dismiss sexual harassment as a non-entity, but in some cases, the difference between flirting and sexual harassment basically entirely comes down to the level of interest that the recipient has. If they're into the perpetrator, it's flirting. If they're not, it's harassment. Given that, surely you can imagine that evolution would favor men who overestimate the degree to which their advances are viewed as favorable by the recipient.
