Here is a
long PDF of a poll of British Muslims taken a few weeks ago. Here are 2 results which I think are particularly important.
First:* Western society is decadent and immoral and Muslims should seek to bring it to an end, if necessary by violent means - 7%
* Western society may not be perfect but Muslims should live within it and not seek to bring it to an end - 80%
* Refused - 1%
* Don't know - 11%
Second:Q: Would you support or oppose there being areas of Britain which are pre-dominantly Muslim and in which SHaria law is introduced?
* Support - 40%
* Oppose - 41%
* Refused - 1%
* Don't know - 18%
In short, read the poll closely, this isn't an black & white community. It seems clear that some people simultaneously support Western society on principle while leaning toward separatism, while a subset, perhaps as large as 10%, are violently and radically hostile to the surrounding society.
