I've noticed people simping for Hamas are almost always people who have an "oppression olympics" belief system/world view. I don't think it's a coincidence, I think it's very much directly linked.
Once you adopt that belief system, you start to believe that the only way to make up for past injustices is future injustices. Once you do that, you're basically foregoing morality at that point. You noticed this in 2020 when a lot of these same people were applauding innocent people having their businesses and restaurants destroyed and burned because "What do you expect these people to do? They're angry and they want justice."
The question is: once someone adopts this world view, is there any coming back from it? This isn't changing your opinions on nuclear energy. That really doesn't involve morality, at least not nearly to this degree. Once you turn off your own morality to where you're willing to accept violence and terror, are you too far gone? If so, we're in a lot of trouble, because unfortunately a lot of people have adopted this oppression olympics belief system. And genuinely believe that someone's identity alone makes support for them necessary, and they're not to be judged on their actions. I still believe the oppression olympics crowd is a minority, but there's more people who think this way today than there were 10 years ago, that's for damn sure.
