Well there's nothing wrong with their religion, so long as they don't go down the path of jihad. The cultural differences, however, are a serious concern. They're turning the UK into a culturally Muslim country and I don't see too many Christians attempting to turn middle eastern countries Christian. I'm not in favor of Christianity being pushed out of Europe, yielding to Islam. America will be next. Again, it's not the religion itself that matters its the culture, the people, the society created by the religion.
