When perverts flash, grope, and harass women in public, it's upsetting to the women, but it's troubling to men too. Because men might have to step up and do something, say something to those perverts.
Now, all the harassment is done out of sight of the "good guys." The pervs can go into the shelters and restrooms without fear of getting punched by a woman's husband/brother/father/friend.
You know how men turn a blind eye to sex crimes that happen in the family home? This is like the public version of that.
