I also don't think this is a helpful way of phrasing your point that we should consider the downstream carrots and sticks of our positions.
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.
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.
I'm sorry it hurts your feelings but real people are losing their homes and livelihoods every day to ever increasing Israeli settlement.
The issue is the circumstances there don't meet the factual criterion of apartheid. That's not a question of feelings. The fact the apartheid label is applied here while it is not emphasized or even applied to non-Jewish countries is a double standard. That fits the definition of anti-semitism.
If I'm Palestinian, I live my life completely according to the rules of Israel (because of the blockade and checkpoints and control of the territory). As a Palestinian, I also cannot vote in Israel and will never be granted the ability to vote in Israel, in order to preserve the ethnic majority of Israel. As a Palestinian I can also have my home taken away from me to make room for Israeli settlers.
That's apartheid.
That is, literally and factually, not apartheid.
