I agree, I don't think Israelis are bad people. They just support bad policy, because they've been convinced it's the morally correct thing to do.

It boils down to nationalism, and in this case specifically Zionism. Which are just forms of tribalism.

The gambit is "You believe x y and z, or you're not on our team." And you just repeat this for every hour of every day of their life through tv, radio, magazines, and movies. And then even the culture itself takes on these values, your mom and dad believe these things, your grandparents believe these things...

Soon you are faced with 'you believe these things, or you don't fit in with the group'. It's tribalism, at the core. Required beliefs to belong to a group, beliefs that are easy to hold (because they don't affect you) and that's it. It all boils down to social pressure, and most of the social pressure is created through the media.

You can't reason someone out of a position they didn't reason themselves in to. You can lead a horse to water but you cannot make it drink. You know?

The only thing to do is lay out true info as best you can, and let the thirsty horses drink and ignore the rest. You cannot change anyone's mind, they have to change it themselves. You can only create the conditions that make it easier for that to occur and hope for the best. You can plant the seeds and create good conditions, but you cannot force the plant to grow.

Many people will live their whole lives and die believing propagandistic falsehoods. It's just something we have to accept about this world. We just have to do our best given what we have, and gently create the mental, emotional, and cultural room for those ideas to exist.

It's a good way to pass the time, anyway
