But, a mistake you make in asking the question is two-fold, one - the Holocaust was not a lesson taught to Jews so they'll learn empathy. It was something horrible and traumatic that was done to them. Two - comparing the Holocaust to what happens in Gaza means you're not aware of what the Holocaust was. Maybe you know highlights such as gas chambers etc, but not what it really was (through no fault of your own I'm sure).
But, to attempt some semblance of an answer. In the same way you wouldn't ask Haitians why their gov did terrible things to the DR and their population - didn't they learn from slavery? Or about India/Pakistan, didn't they learn from the raj? Or any of the African states in conflict - didn't they learn from colonialism? Or Turkey and Syria, Iraq/Iran etc. Then why ask this from Israelis? I hope you get my rhetorical point.
Please don't tell people to harass random jews wherever they live about political stuff they aren't involved in. Thanks.
Please don't let people on hacker news say things like what questions should be asked of jewish people not in israel etc.
They weren't recommending randomly accosting anybody. If the comment had been limited to its first 10 words, I could imagine understanding it that way, but the more important part was what they said right after that: "not HN. The response you'll get here obviously won't answer this question" — in other words, a question like that can't be answered by people who have no experience with it. It doesn't follow that one should indiscriminately harass everyone who does. I know some people are jumping to that, but it's not the strongest plausible interpretation of the GP.
If you had begun your reply with "Unfortunately some people are using this line of thinking to" instead of "Please don't tell people to", it would have been fine; and still more so if you had added some of the information that you included in your reply to me.
