Oh they're real, its not unsual to see someone going from criticising isreal as a nation to going full on anti semite is it? But I still think it was blown out of proportion into something bigger as a stick to beat labour with and I'm sure pro isreal types hyped it up too because the last thing they'd want is a pro palestine prime minister
The 2 or 3 attempted "coups" from the centrists or w/e you wanna call them was probably proof enough that they'd sooner eat and drink their own piss and shit for 5 years than have corbyn in power. Still fucking crazy they'd sabotage their own party from within, but not shocking at all.
I suppose it couldn't have come at a better time for the current labour leadership because aside from corbyn hardcores, no one seems to give a shit due to current circumstances
