Those will always be a small part. If it’s culturally clear what is harrassment and shouldn’t be tolerated, it’s far more likely that 1) there are actual consequences to sexual harrassment because victims feel comfortable speaking up and 2) that bystanders will try to intervene. Both of which make it less likely for anyone to even try.
When speaking up is met with “you dressed wrong”, “he was just trying to get to know you”, that is the core problem. Adding “you were on the wrong train car” isn’t necessarily helpful.
Japans women-only cars are sadly necessary, but the focus should be on making them unnecessary, not adding gender segregation in more places.
And american voters also didn’t get to do anything about the palestinian genocide because there were two choices and pretending there were more is delusional at best. And the choice was between a party unwilling to take a strong stance against it vs a party actively encouraging it and saying they’d help. While also openly wanting to genocide minority groups in their own country.
Well, there is a third choice. It’s the centrist choice of either not voting or voting for an irrelevant party, equivalent to saying “let the others decide”.
