As long as other people are polarized about some issue, you opinion about conflict in Gaza is essentialy a decision to join the "team Israel" or "team Palestine". This choice is absolutely unrelated to the actual people killing each other in the desert. This choice is about whether Joe will consider you an ally, and Jane an enemy, or the other way. With high probability, neither Joe nor Jane are personally related to people killing each other in the desert, and their choices were also based on their preference to be in the same team with some other people.
Data point: you probably know I'm left-wing (in an eccentric way) - and yet, frankly, I'm very "pro-Israel" (although not fanatically so), and think that all the cool, nice, cosmopolitan, compassionate lefty people who protest "Zionist aggression" should go fuck themselves in regards to this particular issue. This includes e.g. Noam Chomsky, whom I otherwise respect highly. And I realize that this lands me in the same position as various far-right types whom I really dislike, yet I'm quite fine with it too.
Yes, I'm not neurotypical. However, you know that I can and do get kinda mind-killed on other political topics. So I'm not satisfied by your explanation.
I think what Viliam_Bur is trying to say in a rather complicated fashion is simply this: humans are tribal animals. Tribalism is perhaps the single biggest mind-killer, as you have just illustrated.
Am I correct in assuming that you identify yourself with the tribe called "Jews"? For me, who has no tribal dog in this particular fight, I can't get too worked up about it, though if the conflict involved, say, Irish people, I'm sure I would feel rather differently. This is just a reality that we should all acknowledge: Our attempts to "overcome bias" with respect to tribalism are largely self-delusion, and perhaps even irrational.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
