Thanks for finding numbers, but I worry about this one confirming bias against Muslims. For example, one could assume that a 60% approval rate among Republicans of Trump means that 60% of Republicans don't like Muslims, but oftentimes in conversations in my home town in Texas I'll hear something like "oh, he's definitely a jerk about the Muslim thing" or "even if he's racist, he's at least doing something about the economy." So I hesitate to assume that "support" means "wholly support."
In any case, I feel this is splitting hairs over numbers. If 30% of the UK hated Muslims, Facebook still wouldn't be requiring "100% silicon valley values" to use the platform. You just can't post racist stuff on it. I.e. those racists have other aspects of their worldview they'd be welcome to bring to the table.
I suspect the number who hate Muslims is small, maybe 1-5% of the population. The number who have misgivings about the behaviour of some Muslims is clearly a lot higher.
