The problem with this particular situation (referring to the original topic) is that the Muslims in question don't understand the concept of immigration, and the subsequent unspoken laws that living in a new country entails.
You are moving to a new country. You have your customs and laws that you have abided by all your life. You must keep in mind that when you are in this new place, it is likely to be vastly different than what you are used to. You are also clearly going to be in the minority. You have to abide by the UK's laws. Not the other way around. This is its turf. It was here first.
