It's more than enough that Corbyn thinks that antisemitism is a vile, indefensible form of hatred and that he's spent decades leading protests against it, voting against it in parliament and sponsoring legislation and resolutions condemning it, and helping the UK's Jewish communities fight to wipe it out.
It doesn't matter whether he considers it "racism" or not- it's more than enough to see it as a vile hatred that must be wiped out. And nobody has to accept the idea that Jews are "a race"- as I understand it, the idea that they are is a bone of contention and disagreement in that community- and the insistence on calling them "a race" is now permanently bound up in the now-permanently right-wing nationalist movement known as Zionism- a movement which achieved its objectives decades ago by creating the State of Israel and no longer has any need either to exist as a movement- since the need for its work as a movement ended in 1948 and the state it created is here to stay no matter what- and no longer has any right to demand unquestioning support from anybody.
There needs to be a clear distinction, once and for all-
It should be universally agreed that, as the clear, simple JDA definition puts it "Antisemitism is discrimination, prejudice, hostility or violence against Jews as Jews (or Jewish institutions as Jewish)".
Every decent human being- and that includes everyone on the Left- agrees with that definition. Why not have it be that and admit that comments about the Israel/Palestine conflict, UNLESS those comments specifically blame Jews as people or Judaism as a set of religious/ethical/cultural traditions for the actions of the Israeli government and its military wing, the IDF towards Palestinians civilians(the vast majority of Palestinians have nothing to do with the armed factions and no means whatsoever to stop those factions from doing what they do) are NOT antisemitism- they are simply solidarity with an oppressed people and an expression of the idea that, with ANY state, there are limits to what people can be expected to defend about what that state does.
