No, I don't mean you personally, I mean the people you might talk to in your circles.
Test them by pointing out behavior that they find abhorrent when done by Israel, and see whether they react similarly (by demanding action against them, denying them a right to nationhood etc). If they do: good. If they don't: it's about the Jews, not about the behavior. And from my experience, they almost always don't, and you really need to press them on the issue until they'll halfheartedly agree that yeah, that is also not good what the non-jewish country does. Case in point: the "Gaza Freedom Flotilla" tried to sail from Turkey to Gaza to protest Israel. It's like starting a Journey in the Third Reich towards Stalin's Russia to protest the inhumanity of Finnish policies.
I'm sure you're familiar with the idea of "Driving While Black". Israel is "Being A Country While Jewish". Some cops will pull over Black people all day long and claim that the color of their skin has nothing to do with it, it's just about how they drive. But you'll see them letting white drivers do all kinds of stunts and will quickly understand what the deciding factor is. You can do the same with people's opinions on Israel.
