There is an upside: oppressing people who consistently engage in antisocial behavior is good and necessary.

Imperfect enforcement is a feature as often as it is a bug. You can't make "antisocial behavior" in general illegal but you can make certain behaviors (loitering, public intoxication) illegal and selectively enforce against only those who are behaving in an antisocial manner. Of course the other edge of this sword is using this discretion to blanket discriminate against racial or class groups.

It's not that surprising. Ask the average Jordinian about their opinion of Palestinians some time. Ask an Egyptian or a Syrian if they think their countries should take in Palestinian refugees. The regional Muslim Arabs all hate them too.

Israel wasn't bombing those neighborhoods for revenge, they were doing it because Hamas build militarized tunnels under dense civilian neighborhoods.

People with historical trauma are far more likely to inflict further wrongs than people without historical trauma. This is the case for individual trauma too. It has always been this way.
