Eve Garrard at normblog makes a brief but powerful point about the nasty practice of equating present-day Israel or America with Nazi Germany:
…until there’s some evidence that America, or Israel, or the Bush administration, or the Sharon government, is setting up factories of death in which millions upon millions of members of hated ethnic minorities (or even majorities) are deliberately and hideously tortured and killed, then claims that America or Israel is equivalent to Nazi Germany will amount to ways of denying or diminishing the fact and the horror of the Holocaust.
