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. Some of those other links are vile though.
