No one has said men don't need to be afraid of being raped. The point is men don't need to be afraid of false accusations that they raped or sexually harassed someone. The rarity of such a thing is about on par with a guy dressing as a woman to assault women in the women's restroom.
The claim of "rarity" simply isn't supported by careful examination of statistics.
But regarding that having-no-fear about false accusations, tell that to those
Duke lacrosse players. But there's more.....my maintenance guys have been
regularly flashed by female tenants (apparently a problem with university
students), & the fear that this could balloon to greater harassment is reasonable.
And yes, I consider flashing them to be sexual harassment.
You won't convince me to be sanguine about such risks posed in the workplace,
even if the risk is supposed to be statistically unlikely. I did have a false accusation
of a sexual nature leveled against me once. Did it ever happen to you?
