People calling for my people and my nation to be wiped off the map. (And I don't try to get Hacker News blocked by their ISP or cache provider. I understand that an open forum will have speech like this.)
I'd like to point out that I understand what's "vile" to one person isn't to another. I've had my posts reported as "hate speech" on reddit for saying that "the Fat Acceptance movement is dangerous" and that "Obesity is wrong."
Banned speech should have a very high bar -- direct, specific threats of physical harm.
For the first link at least, they seem to be talking specifically about parts of Palestine occupied in defiance of international law and agreements being returned to them, not Israel broadly being eliminated. Israel/Palestine border disputes are massively controversial, so I don’t dispute people do say things like your summary of the comment, I just don’t believe the comment you posted is that. In fact I think your summary is a bad faith reading of the comment.
