The point of calling Israel an apartheid state is of course not to claim that Israel is identical to what South Africa was. The point is to emphasize that it is the same racist and supremacist ideology that permeates both systems. In South Africa, you had white people (Boers) dominating and oppressing colored people. In Israel and the occupied Palestinian territories, you have Jews dominating and oppressing Palestinians.
The Palestinians agreed in the Oslo Accords t govern themselves. They don't vote in Israeli elections, and Israelis don't vote in their elections (if they had any).
Israel denies citizenship, voting rights, and equal rights to Palestinians (who still have to live according to the law Israeli citizens decide because Israel controls their territory). And the entire basis for doing this is that Jewish people must be the ethnic majority in Israel. It's literally apartheid on ethnic lines.
