Part of the antisemitism is the CONSTANT reference to the holocaust and use of holocaust analogies and terminology to decribe the Israel-Palestine conflict.
Israelis/Jews and Palestinians have been doing a lot of shitty things to one another for the best part of a century now (and, yes, Israel does have the upper hand now and bears more responsibility and is responsible for more abuses) but it has not ever reached the point of or even come close to the holocaust. There is so much else which it could be compared to but, no, always the Holocaust.
So, it's Israel is committing genocide (so, hey, maybe you jews shouldn't bleat on about own genocide since you're dong the same)
Or, Gaza is the same as the Warsaw Ghetto. Where the Nazis would send off transports of Jews to death camps, intentionally starved the population with children starving in the street, used slave labour, intnetionally allowed disease to spread etc. Gaza is bad, don't get me wrong, but it's not the horror of the Warsaw Ghetto. But, no, constant reference to the Warsaw Ghetto.
Or some weird expectation that 'Israelis should know better than to do what they're doing to Palestinians' as though genocide is expected to make you nicer (rather than perhaps an understanding that genocide is not character building and, actually, common trauma means you might not be so tolerant of someone threatening your life)
Or the 'zionazis' you seen thrown about.
Or the catoons in the papers depicting Israeli solides as Nazis.
It's continuous. And it didn't happen to the Burmese with the Rohingya genoice. It didn't happen to China. It didn't happen to Russia. Only Israel gets the constant holocaust/nazi analogies. Why? Antisemitism. Pure and simple.
So for those who say 'Oh, I've never seen antisemitism in the UK' just look at posts on mumsnet when things flare up in Israel/Palestine. You'll see it there.
