Fend themselves off from what attack? Oh yeah, a straw (wo)man attack. How is your argument not part of "the culture that breeds feeling of ownership by men of women"? Simply spectacular invocation of rape culture arguments, not that I've ever seen this topic discussed rationally.
No one needs to be trained to a military standard to fend off any type of vicious attack that might occur, because except in ultra-rare occasions they do not happen in first world countries. The true danger in our society is not physical at all, but mental- fear cuts down many lives by silently shaving off a million tiny slices, and those who fall victim to it never even knew they had a choice, or a chance. They just listened to the unspoken messages on TV.
