There is NOTHING that Muslims will do that will wake liberals up. They will be apologizing as the knife saws through their throats. The reason: The see Islam as the force that is going to put an end to Christianity once and for all.
I'm not saying that you're wrong on the Leftists' reaction to their favorite religion targeting them (look at Communist Massachusetts); however, I think if one ridicules the Leftists when the Muslim terrorists attack them instead of offering them sympathy, it might go some ways in putting a brake on the lib/commies utter appeasement of the religion of the demon possessed paedophile.
