That's half the problem. Britain has bent over backwards to accomodate all kinds of practices of different cultures in the name of Political Correctness. Nobody's had the guts to stand up and say, "You're here now, you do it our way".
We once had an empire that encompassed much of the Indian subcontinent. One of the common Hindu customs was Suttee, which meant that when a man died and was cremated his widow was supposed to throw herself (or be thrown) on the funeral pyre and be burnt to death. The British Empire made it illegal and, eventually, it was stopped.
Today we are aware of these so-called "honour" murders but we persist in almost dignifying them by referring to them with the word honour. We stand by while young women and girls are treated, in their homes, like 2nd class citizens. We tolerate women (if we can be sure they are all women) walking around covered from head to foot, though we'll ban a small child from a shopping mall because he has his anorak hood on his head.
Maybe if this country stopped trying to be all things to all men, maybe if we said, "Live like us, look like us, do as we do - or leave", it might help to stop the worst excesses of these "cultures". Go to Saudi Arabia and try to live, dress and behave exactly as you do here. I can assure you, having lived there myself, you won't last long.
