“the biggest factor is our biological programming to be protective of women”
Then why is there such a need for battered women’s shelters?
Women don’t need to be in a frontline infantry outfit simply because they’re not as strong as men, but women can be very effective in other military roles
That is no more a contradiction than asking why there are jails for the reckless drivers when man is programmed for self-preservation. And you should keep both abusers of women out of the military, as well as their prey in close quarters.
