The difference I’ve seen is that people generally seem to be able to call out the crimes or bad behaviour of any of these governments without being called ‘racist to _____ ethnic group’. It has to go both ways, people need to stop blaming the crimes of Israeli governing party on the Jewish people as a whole, AND supporters of the that party’s actions need to stop labelling any criticism of them as antisemitic.
I don’t know what you think science is but this is not it. Your experiment is like building a go kart and acting like you’re on par with auto-industry engineers.
