For your 99.9999%, I would offer a confident 90%, if we loosen the terminology to 'sympathising with the extremists' I would offer you 80%.I wouldn't be worrying if I lived in the UK either. These valid reasons that many seem to cite as cause for concern, appear to me to be totally overblown and out of proportion. I would imagine that 99.9999% of the Muslim population of Britain want to just get on with their lives without pushing any agenda whatsoever. It is the tiny minority that some people are worked up about at the moment and if I have a concern, it would be to any overblown, disproportionate reaction against them.
