36% of Muslims living in UK believe if a Muslim converts to another religion they should be punished by death. But I'm sure you will find some way to nitpick out of this and tell me that these Muslims don't count. Right?
Also, in case you intellectual honesty doesn't allow you to figure out, these are that Muslims that in their great majority are supposed to be already westernised since they actually lived for a long time (or were even born) in the West.
