It's one of the most discriminatory non third world country, if not the most. You literally have citizen of the same country treated differently depending on their last name and/or their religion, and worst than that, they don't even have the same rights.
It's not some "soft" racism like in the US where, in theory, everyone is equal in term of rights and in front of the justice, in Israel you have laws that only applies to non jewish people, they're not even trying to pretend, it's institutionalized and a source of pride
Israel/Palestine is similar to what's going on in Ukraine right now in many aspects but everyone seems to ignore that. It's just further away, happening slower and is committed by an historic ally.

It's Israel, who's surprised.
> Israel is slowly losing its support in the free democratic world where people believe in the inalienable universal rights of individuals and are less and less willing to turn a blind eye to such institutionalized racism.
If using tanks against children throwing rocks or white phosphorus bombs over civilians didn't do it I doubt anything will. I'd recommend you to get in touch with a Palestinian and ask them about their life. Israel has been committing war crimes every now and then for decades, they're smarter than the Russians though, they do it bit by bit.
Talking about discrimination, don't read about their border control interrogations, if you have an arab sounding name, talked to a person with an arab sounding name or visited cities with a large arab population during your stay be ready to spend 4 hours in a small room with a few unpleasant people asking you about every single minutes of your trip.
