You have a point exposing the differencies, but by doing so you miss the main topic of the story. And that is the weakening of ethical standards that apply to all people, and the consequences of singling out a group, making them fair game for discrimination. And, sorry, that's what the rest of the world sees nowadays when watching Israel's policies in action. The kind of collective punishment conducted by Israel against all Palestinians is ethically wrong. That all Palestinians support terror, which is the de-facto base of the government's discrimination of those people, is one of those horrible fabrications. Siegman is right to point that out, because that's really not much different from the Nazi's claim that all Jews are capitalists who are parasites of hard working German workers. Neither the Nazi's claim, nor the Israeli one are true. And while Siegman doesn't say anywhere that Israel is like Nazi Germany, he correctly points out the disturbing paralells. This should be taken as serious food for thought, and not simply being dismissed just because the analogy isn't perfect!
