That is true everywhere, drunk or affected men are overwhelmingly more likely to harass women than sober men are. Subways here in Europe are full of pretty women, they don't go out of their way to take a car any more than men are, when I count gender on subways there are usually more women than men.
When was the last time you saw women avoid grocery stores because they are afraid of getting harassed? Well used public transit is that level, it isn't something women worry much about compared to many other much larger threats. There is no reason at all for public transit to be worse in terms of harassment than grocery stores are, its just that USA choose to let their public transit become shit.
Grocery stores are different because bums aren’t allowed to sit around there waiting for a woman to come by for them to harass. If they were, I’m confident many would object.
It’s clear that you don’t have much concern for the harassment experienced by those woman columnists you read, so I don’t think there much more I can say here. I imagine if you were to have any direct experience at all with the problem, your position would be different.
That all said: what’s your upside? What do you gain which you consider to be worth these women whom you do not know sacrificing their safety?
