You just proved my point. Men are undoubtedly stronger than women. Men are evolved to "spread their seed". Some men will take advantage of women whenever possible. Therefore a woman walking alone at night is not safe. Therefore a woman needs the protection of a man. You cannot change the behavior of every man. You can change some of them, even most of them. At the end, some men will keep being violent. Therefore a woman without a man's protection will never be safe. And this is already burned into their psyche.
