There is an interesting and delicate conversation about how a twenty-something engineer in the military ends up frequenting anti-military and anti-democracy subreddits. I think that fits in with hn.
There is another interesting and delicate conversation about what that person thought about Gaza and about Israeli Jews, and where those ideas came from. He posted on Reddit that Hamas's stated intent to destroy Israel - where 7 million Jews live - would not count as genocide. That is a higher percentage than the extermination of 6 million European Jews in the Holocaust, when there were more Jews alive than now.
He based this on the belief that Israel is a US and UK colony, which is hard to take seriously either literally (since it isn't) or figuratively (since none of the many non-middle-eastern waves of Jewish refugees came from the US or UK).
He also had a deeply held belief that the violence killing 1% of Palestinians in Gaza IS a genocide (and I think it's safe to assume that he fully accepted Hamas's claims that 30k people have died, and fully rejected IDF's claims that 12k of those were Hamas militants). So deeply held that he burned himself to death over it.
To me, the inconsistency of holding those two beliefs so strongly at the same time is a sign of antisemitism believed more deeply than I personally believe in anything. And that contradiction does not survive a moment's rational thought - to me at least. Which makes me assume that someone whose profession is built around thinking rationally was simply unable to think rationally about the Israel-Gaza conflict and see the inherent asymmetry of what he was saying.
So I think there is a discussion here. Not about whether he was right that the devastation in Gaza amounts to a genocide, or right about whether democracy is evil, or right about whether America is evil. But the limits of rationality compared to how engineers usually think about themselves, and whether we are more or less susceptible than anyone else when it comes to online echo chambers.
And it is incredibly hard to have that conversation without getting into flame wars. Or projecting our personal beliefs about the Israel/Palestine conflict to the point that it prevents useful discourse.
