The correct response to the scandalous assertions of Toaff is not "So what if there was a small extremist sect with bizzare customs". If you don't understand so what, then read the beginning of your own article: Because the Jews have always been held collectively responsible for the actions of any one individual, let alone any group. The correct response is: "There was no such sect and there was no such ritual and no such murder, Toaff has not proved any of his claims and he should take them all back without equivocations and excuses". The problem is not what happened 500 years ago. The problem is that the same virulent antisemitism is spreading again today, particularly in the Arab world, with the same wild and hairy conspiracies as in the old times.
