It’s interesting that you mention Jewish Trump supporters, because in the UK, Labour political activists have been pilloried for simply inferring that such people exist.
To state that right-wing Jews exist is so offensive to right-wing Jews, that they consider the statement antisemitic; and yet it is the left-wing Jews who are ‘self-hating’ and ‘kapos’ according to them. I feel like I’m taking crazy pills.
It’s also interesting that accusations of antisemitism have come largely from the Right, who are simultaneously coolly unconcerned about actually-existing antisemitism, or its victims.
