The standard controversy over each Islamic terrorist attack is "do we blame Islam, or is that Problematic and Islamophobic and Wrong?" - isn't it more likely to be leftists rallying against Islamophobia after each attack causing the rise in public opinion? Doesn't require as much psychologizing, at least, since it rests on people believing what they say they believe.
Of course, these studies are frequently bogus, so my real theory is "mu".
