I'm pretty sure you're posting in good faith, so a few things:
1) I haven't seen anyone say that Corbyn is going to literally going start another final solution (that was not how I interpreted Ray's post) and I certainly haven't said anything to that effect. Nor would I because obviously Corbyn isn't going to start some sort of second Holocaust.
2) There is middle ground between "Jeremy Corbyn is not an anti-Semite" and "Jeremy Corbyn is literally the next Hitler."
3) That said, it's hardly unreasonable to suggest that at the more extreme end of possible scenarios is one where Corbyn gives the appearance of tacit approval of violent anti-Semitism more or less the way Trump did of violent racism when he tried to "both sides" Charlottesville. That isn't the most likely outcome imo, but it wouldn't exactly be way off-brand for Corbyn either.
4) On a related note - and this next part isn't directed at you, so much as it is an expression of general frustration with certain maroon-avatars - it's really starting to get on my nerves how certain folks on Atlas seem to feel every Jewish poster owes them an explanation for any dumb thing they heard another Jewish persons say on Twitter once. We're not a frigging hive mind and not all Jewish people feel the exact same way about every issue.
I may have misunderstood Ray, but I seem to remember similar statements from him that seemed to suggest he feared Corbyn would drop a nuclear missile in Israel. The issue is that the AS that Corbyn has surrounded himself in isn't that kind - which in this country remains the domain of the far-right, a faction which - regardless of what you may think about Corbyn - has no truck with the Labour leader, and despises him for many reasons. Corbyn's AS is more the "muted" kind endemic in the middle-class of this country (and probably most countries) and in his case is wrapped up around the obsession with supposed Israeli influence. Definitely something problematic that should be pulled out, but a clear step (in my mind) from Trump's "good people" remark about those chanting "Jews shall not replace us".
Definitely agree with the bolded. Throughout this whole debate, I've tried to read the opinions of British Jews throughout the spectrum and they obviously are not even remotely operating under a hive-mind. Rest assured, if it gets to the stage that Jews across the board are leaving and casting aside the party, I would follow them out. No policy plank is worth that kind of garbage.
A third and, mercifully you may well say, final point now: an additional issue is that for a brief but significant period in the 1950s and 60s (a very important time in the history of the Jewish community in Britain for obvious reasons), the Labour Party was one of the main bulwarks against antisemitism in British society. There was no easier way to get on the wrong side of Gaitskell or Wilson than to be caught making an antisemitic remark: some otherwise promising MPs had their careers derailed for doing so. This was a long time ago now, but history is history and it has added a real sense of betrayal to what has happened: e.g. that the institution that Grandfather voted for is now like this being widely seen as adding a grotesquely personal insult to what would be felt as an injury no matter.
didn't Bevin have problematic views, or am I mistaken? Although I suppose he was the old guard by that stage anyway.
