Those groups are horrible and dangerous but they exist only in their regional contexts and so are hardly relevant in the U.K. There are Muslims in the West that sympathize with them, but they are (a) in the minority, and (b) fools who couldn't organize themselves out of a wet paper bag. Get three of them together and the third forms a splinter group. Which is why the over-focus on them is sensationalist nonsense; you could find 'shocking' views similar to theirs by trawling local pubs.
