Because the question is not relevant. You miss the point. The attack isnt on Jews, its on Laws thats say denying the Holocaust is a capital offense. The Holocaust could have involved ginger kids, and it wouldnt have a made a difference. The issue is free speech, however repugnant, not Jews per say.
The relevant question is, why is it ok to offend Muslims, but not ok to deny the holocaust and offend Jews among others?
Im not for offending anyone. But free speech shouldnt discriminate. Everyone is an open target when it comes to free speech in a free society.
