What's the alternative to multiculturalism Ubes? The French are much less 'multicultural' than we have been, look where it's got them. Perhaps multiculturalism has helped limit the Islamic inspired terrorist attacks to 2 incidents causing deaths so far in the UK. Perhaps the fear and hatred here is less than in other countries, precisely because their beliefs are given some measure of respect (not from me of course). How on earth do you force integration?
The issue, at the moment, is with a particular twisted form of Islam, which, as Nines pointed out above, even ensnares western educated doctors and professionals. My views on all religion are pretty clear, and Islam is a particularly repellent example of it, but big generalisations may not help. The exception to this is probably the entrenched abuse of women. I might be tempted to say 'that's it, no more Muslim immigration of any kind except for heavily vetted genuine refugees within the limits we have set ourselves' because the attitudes to women are fundamentally opposed to our 2016 UK values. Although given some of the stuff you put on the joke thread I'm not sure that this is strictly accurate......
Where Islam seems to be different is there is less social integration over time. We still see concentrations of West Indians, Hindus, Sikhs, Jews in some areas but nothing like the levels of Muslims, and of different nationalities within Islam. Yet I work with Muslims in my company every day, and their faith never even crosses my mind.......
As Matt and Nines have pointed out we have a massive conundrum, how to deal with this without becoming the thing we despise.
