Not as dumb as it might seem. In many civilizations, hair ( female) is considered to have some "sexual" element attached to it. Today we all wear covers on our pubic hair, at least in public. Where do you set the boundary??[/
Hair on the head doesn't have quite the sexual connation as pubic hair or breasts, it doesn't usually arouse in quite such an immediate way. There is a good reason to cover up 'skin' as extremes of heat/cold damages it. Modesty is nice but you can't totally deny biology, it's going to come to the point where these men go berserk at the sight of a wrist or ankle!!! The more sexuality is 'forbidden' and 'hidden' the more it will become distorted. This why you see scenes of Middle Eastern men turning into rapists and sexual molesters when they reach places like Germany and Sweden. It's not as though extreme Islamic clothing has stopped sexual misdemeanours in Islamic countries, the rapes and sexual abuse are just as prevalent, it's just not reported as much. Happy medium usually works for most things.
Believe me, the ones who cover their hair won't be happy until you do too....
Sadly you are correct. There are parts of London and Birmingham that are 'no go' areas if you are not seen to be following Sharia rules and Sharia rules are strict.
