While I agree that many women dress provocatively, we also (as men) need to change the way we "see" women... I fully understand the physiological differences between the way men and women are sexually aroused, but there is also the "self control" aspect of it.
If I cannot see an attractive woman, dressed provocatively, without immediately thinking lustful thoughts, then it is my contention that there is a flaw in myself... otherwise, we need to go the way of the strict Muslims... cover all women from head to toe.
Men need to learn self control in physical and mental areas. I can look at an attractive woman, dressed provocatively and not lust... but it is a mental/spiritual issue. While it would be "better" to not deliberately put myself in those situations constantly, the occasional need to do that should be controllable through mental/spiritual discipline.
I also believe that it is normal to see an attractive woman, and appreciate/enjoy the fact that she is attractive, with out thinking lustfully about her.
