Nobody likes Muslims except for Catholics and Muslims: The General Social Survey asked Americans in 2004 about they felt about Muslims. Answering between zero to 50 indicated "cool," and 50-100 indicated "warm." Here are the means for people of various religions:
Warmth toward Muslims
So Catholics are the only group with a warm average. Protestants are neutral, Jews are clearly cold, and people with no religion are slightly cold. (I checked to see how coldly Muslims feel toward Jews--their average is 44.2.). Muslims feel warmer toward their own than any other religious group. (In a previous post, Jews and Catholics were around 80). Maybe this is why so few are outspoken against their terrorist co-religionists.
