As a counter-point to the above, it has not been my experience at all.
I have encountered people with a range of views on a range of issues. Some people are lovely. Some people, well, aren't. Just like every other population. But at no point have I encountered universal antisemitism or other hatred against another group.
Maybe other posters have been unfortunate and been surrounded by unpleasant people. Those people's views are not representative of Islam, any more than I could say the EDL's views are representative of Christianity.
