They think like a liberal. They're better than everyone else, not because of any true virtue or just action, but because of their own narcissism. The fact that they're objectively evil in their thoughts and actions is almost entirely lost on them. Because they act as they do, those actions are the actions of the virtuous in their minds. Were someone to act as they do towards others towards them, that person would be irreconcilably evil. They are hypocrisy incarnate.
A few years back during the Iraq war a number of jews at my office were watching video of an Apache helicopter murdering civilians. They were cackling with glee as an ambulance arrived and everyone in it was killed as well. I asked them why they were so excited that random arabs were being killed. They said arabs were not people, but subhumans that needed to be exterminated. Why I ask. Because they attack the IDF they respond. I ask if they feel it's because Israel stole their land. No, they say, it's their land and the arabs should be wiped out for daring to fight against them.
That's how they see themselves.
I can best describe it to a normal person as the way we look at mice. If they're in our house eating our food we kill them and think nothing of it, even if we built our house on land that 1000 generations of mice have lived on.
