This post is a footnote to Eve's immediately below. Amongst the questions she puts there is whether saying that Israel is committing genocide can be regarded as anti-Semitic. It's a very good question. Or, to put that slightly differently, it's the simple truth.
Here's an angle on it that may not be immediately obvious. Other than Holocaust-deniers themselves there are few who would doubt that Holocaust-denial is a form of anti-Semitism. One can reach this conclusion by different routes: for example, highlighting the attempt by proponents of the historical lie here to bury the memory of the calamity visited upon the Jews of Europe; or else focusing on the implication it carries of how bad the Jews must be to be willing to put about so gross an 'exaggeration' of their own suffering. Either way, no one other than those actually caught up in the lie can fail to see it as a hostile slander against the Jewish people.
Denying that the Jews were the victims of a genocide now has its counterpart in the allegation that the Jewish state is perpetrator of a genocide against another people. And this is not a case where the evidence is borderline. Just like Hocaust-denial, genocide-assertion as applied to Israel vis-à-vis the Palestinians bears no relation to any serious historical evidence about the long conflict in the region. It is a blatant historical falsehood - the blood libel on a spectacular scale.
Genocide-assertion with reference to Israel should be seen henceforth as the twin of Holocaust-denial: a not very covert form of anti-Semitism that disgraces its proponents.
