I'm sure they will in time but it's shocking how ingrained it is. I meet and deal with Muslims every day and they tend to be incredibly friendly welcoming people (much as the majority I dealt with back in the uk were).
Having said that, my Mrs teaches 6 year olds in a private school. Her children are all Muslim except one and three times this school year she has been given koran's by her children. I thought that was really sweet until she told me what these six year olds tell her, which is uniformly along the lines of "we love you miss so we want you to be a Muslim otherwise you will go to hell (the actual term used was "the place of fire").
Now if that's not fucking scary coming from the mouth of a six year old I don't know what is!? The parents she deals with are again very very nice people, but what are they telling these kids at home?
