Yeah ... I guess it's the same kind of instinctual thing that requires women in some cultures to have to cover themselves from head to toe, because, you know ... men are, by pure instinct, attracted to them and would never be able to control their sexual urges around women who showed too much.
The same instinct that men who beat their wives/girlfriends to a pulp for sport have, right? That protective gene all men seem to have.
So I guess that you're cool with requiring every female between the ages of 18-25 to register with selective service? For equality ya know.
