Well, there are places that require you to wear a shirt anyways. As for the people saying they don't want to see topless women, well, I don't want to see fat chicks wearing revealing clothing either, but can I tell them to wear more clothes they either don't have or refuse to wear? Yet, no one says fat people have to cover up. If you don't like seeing particular sights, then simply don't stare at them. Go read your porn mag or something.
As for women going topless, if they were allowed to, then this would be a choice--if some women don't want to go around topless at a swimming pool, then they don't have to, it's their choice. If they want to, they shouldn't be bothered about it either. I guess this also goes back to the argument about skimpy clothing--if you know it's going to attract attention, either don't do it or be prepared for it.
Because I'm not much of a woman, can someone tell me if seeing a guy topless might "arouse" them?
