I think right wing antisemitism is easier to tackle because it's more straight forward.
The left-wing antisemitism is sort of like a self feeding virus. The people doing it have theory identity / persona wrapped up in being 'anti racist' or particularly good people immune to racism so they can't see that their behavior is perpetuating hate.
To justify it in their minds, they obsessively demonise Jews as evil - white colonisers, baby killers - whatever, and then they use that to create a sense that Jews deserve it and have it coming.
That creates more hate, and more hate and as it escalates and you see arson, beatings, stabbings, they just carry on justifying by demonising Jews more and more and more.
They're not skinheads or thugs- they're often regular people. NHS workers, teachers, university professors, journalists, politicians, human rights activists and they fit everything around protecting their psyche from admitting they're racists.
Of course there's been thousands of years of the same excuses: they killed Jesus, poisoned the Wells, drink kids blood, are capitalists, communists... the deal is always the same, and it's just excuses. And yet they think they're right this time.
What I find most grim is how if Jewish people try and speak they scream at them that they're genocide lovers or baby killers. I mean, what are Jewish people meant to do with this behaviour?
It's a really horrible environment right now in the UK. Ugly.
