But that's not the question - who is more likely to harm you on a crowded subway.... The question is if a woman is walking alone in the woods, who would she rather encounter. Statistically, the bear is much less likely to harm you. And, if one did, at least most people would believe you and feel bad that happened to you. Not so of most women attacked by men.
In truth, a large number of women are raped, beaten, or killed by their own partners/former partners and family members or by other people in their lives that they ought to be able to trust such as dates, co-workers, and bosses. Strangers aren’t the only danger.
Like so many other men reacting to this scenario, you are (perhaps intentionally) missing the point. A culture where masculinity is in large part constructed by being dominant, aggressive, and having control of the women in your life means that male violence is an epidemic - against other men, but also against women.
85% of American women start getting sexually harassed in childhood, some as young as 9 or 10.
1 in 3 will be raped
1 in 4 women has been the victim of severe domestic abuse
There are cultures where this shit doesn't take place at anywhere near these levels. The issue isn't men, it's men in a patriarchy who have been socialized to view violence and control as "manly." How about you put some effort into challenging and changing that rather than trying to convince women they should disregard their lifelong experiences with lack of safety.
