I don't want to be called "leftist" because I don't want to belong to any tribe. But I do embrace a lot of the humanist ideals of the so called "progressives" and I think they might have some moral ground in here. But feel free to call me whatever you want.
In my perspective, the oppression in Iran is different from what is going on in Gaza. It is more like what happens in Belarus, Russia, Cuba, Venezuela, Turkey and Myanmar: it is an authoritarian government killing and oppressing their own people. I am not American but if the American government wants to kill innocent people in Minneapolis that is an American problem that the Americans should solve, because I respect the US sovereignty.
OTOH, I am ok with western interference in Gaza because Zionism is a racist project from one ethnicity against other, it is the racist government of a racist people committing genocide against another ethnicity. It isn't an internal issue of a sovereign state as much as apartheid wasn't an internal affair of the South African regime.
