No doubt a few are. But the way you word the question, you make it sound as if every Muslim in the UK is supporting the Taliban which is a million miles from the truth. It's a tiny, tiny minority. There are extremists in pretty much any group, anywhere.
Are US Christians really supporting the demise of the polar bear? OK, this may not seem such an important issue to you, but it has the same thought structure. It's not because they're Christians (though it may relate to their belief that they have a divine-given right to oil), and it's not very many of them. So to word it like that is not exactly helpful.
