"I'm fleeing from religious persecution."
"I will now religiously persecute the Indigenous people of the land I fled to."
Even if every single Israeli fled Islamic states, they've been pretty eager to do the exact same things they fled from. So why should I give them any more sympathy than the supposed evil Islamic regimes they escaped? They're just as hateful and intolerant of other people existing. You cease being the victim the instant you inflict the same abuse on others when the power dynamic flips.
