I think the reason is down to culture disparity. The UK has a high population of Muslims, and this population of Muslims is generally not spread evenly, their are whole communities with a high concentration of Muslims. If I go to an area of my city called Spark Hill, I will see it is an almost 100% Muslim community, nothing like where I live which is predominately white Christian.
Obviously I think this can cause tensions. In countries where the population is total Muslim they don't have so much tension between communities because they are fairly similar. But having a Christian community a few miles away would cause more domesticated tensions.
Meh. I haven't exactly put that too eloquently, but you know what I mean.
