People justified their anti-Muslim hate after 9/11 with similar statements about polls saying most Muslims saw Bin Laden in a good light, and have anti-West views.
Not saying I agree with any of it, but I find the parallels illuminating. If anyone wonders why there's more anti-semitism now, s/he can perhaps compare it with how all Muslims are condemned as being members of a barbaric sect after any terrorist attack (yes, even attacks where the perpretator doesn't claim to be doing it for Allah).
