"you may think there is a place in the modern social life of the United Kingdom for Sharia Law, having women treated as second class citizens, FGM, forced arranged marriage, religious intolerance, loss of freedom of speech, censorship, capital and corporal punishment enshrined and revered by the followers of the "Religion of Peace" as demonstrated by ISIS "

Er, no. I don't think there is a place for any of those things. However, you didn't mention them in your post, you seemed to be inferring that because a ruling elite had made life hell for the citizens of any given nation, those citizens should stay there and endure the suffering visited upon them rather than come here, where the things you listed in your sentence above are, supposedly, protected.

The "the main actors" don't give a shit about those people but others do, and we offer them refuge from their persecutors. Luckily not everyone is like Farage or the tories.
