Criticising Israel can be antisemitic. Just check out the IHRA definition of antisemitism . Basically you can't say that:
- Israel is a racist endeavour
- Comparing Israeli policy to that of the Nazis.
- Say that they use murder (especially of Christians) for ritual purposes.
Even in their worst excesses, any legislation cannot change a deeply held moral position. Oh they can try, but the best (worst) they can do is legislate action and communication.
