I don't deny for a second that men and women are different in many way. I don't deny for a second that the presence of different chemicals and hormones causes us to react differently in certain situations.
What I do deny, and vehemently, is the outdated idea of 'weak women' who need a man to protect them. Surely all you need to do is look at the many armies around the world who have and have had women serve in front-line capacities.
If you think that a Red Army soldier, or an IDF soldier, is not threatening to you based on her tits, woe to you if you ever get on her bad side mate.
