Sex-segregated transportation to decrease harrassment

Many cities across the world have resorted to creating "Women only" transportation "to protect" women from being harassed, at least when they are commuting.
While I can see why this is beneficial for women in the short term, I am worried about the inherent meaning behind this measurement-- we need to segregate women in order to protect them, because they are weak and they can be harassed if someone choses too.
I would like to see actions that convey the message " No, you cannot harass any human being, regardless of their sex, age, and race (to name a few.)"
