Another interesting result from Pew's "Islamic Extremism" survey: Americans are, compared to other Western countries, pro-Muslim! Only 22% of Americans surveyed admit to unfavorable views of Muslims. I suspect that many people who hate Muslims won't admit it, but the fact that they are reluctant to admit it itself indicates the direction of social pressure.
So where are people most willing to openly declare their unfavorable attitudes towards Muslims? The Netherlands. Fraction who regard Muslims unfavorably: 51%.
