Well, I'm quite elderly too! But, studies have shown that something like 20% of Muslims have - what you call "fundamentalist" beliefs - and that is a hell of a lot of people.
   But, to say that the UK isn't facing a problem with Muslims who don't believe in a lot of basic Western values, shows a definite " head in the sand" mentality.
The UK has accommodated so many different cultures/ethnic/religious groups over the years, but it wouldn't be unfair to say the Islam has been/is the most difficult.
