These NPCs are literal fucking morons. They don't have any values or ethics or beliefs of their own, only what they glean through osmosis from the mob mentality. Like the BLM riots of 2020, they just want to be seen to have the "correct" moral alignment.
Five minutes ago, these were the "punch a Nazi" people. "I was just following everyone else" is how the original Nazis rose.
The jihadis and terrorists love that these useful idiots are running interference for them, though.
Guaranteed that the ringleaders are the true believers, the Islamic supremacists eager to destroy Israel and exterminate the Jews, as Hamas themselves have declared. Some other proportion will be agitators who just want to engage in violence and destruction and are there for when it happens. The rest are just mindless drones who think they're going to be the stars of a cultural moment.
