Thought this was worth calling out specifically, since while I'm not quite on board the "it's as bad as south africa" train, it's flat out false.
For example all Jews, as well as their children, grandchildren, and spouses, have the right to move to Israel and immediately gain citizenship. Non-jews don't have that right. So an Israeli Jew has the right to bring relatives in, immediately and as full citizens. An Arab Israeli does not.
For another example, Israeli Jews have compulsory service in the military. Arab Israeli citizens do not.
For another Israel has laws that allow some Jewish citizens, but not Arab citizens under the otherwise identical circumstances, to recover land lost during the 1948 war.
For another the Nation-State Law of 2018 cites "The right to exercise national self-determination in the State of Israel is unique to the Jewish people" so Jews here are called out specifically as having a right unique to them alone (there's other problematic stuff in there but it's the most obvious one).
There's also a slew of laws that are effectively discriminatory against Arab citizens in practice (the citizenship and entry law regarding spouses who are Palestinian for example, which even the UN unanimously resolved violated international treaties against racism)...and then a slew of defacto enforcement of laws that are also demonstrably discriminatory- for example Arab citizens tend to receive heavier jail sentences than Jewish ones for the same crimes, are more likely to be convinced of serious ones that Jews, and are denied bail more often than Jews. Schools in heavily Arab areas also tend to be varsity underfunded compared to those in predominately Jewish ones....and the list goes on and on.
