This is anti-Semitism:
“I'm going to hate an entire group of people for their beliefs. I'm going to enforce my own beliefs on this group by mocking and ridiculing them, by harassing them, by beating them up and/or killing them, and of course this is all okay because I disagree with their ideologies. It's okay to murder and to bully and to hate someone that you've never even met, merely because your religion is not the same as their religion.”
If you don't understand what's wrong with that, then you have no moral compass.
