Not a fan of bringing up Hamas. They're not especially relevant, because tankies and real leftists alike both stand united against Israel's ongoing genocide and long-standing apartheid state. Hamas might use terroristic methods, but their cause is every bit as just as Irish republicans, black South Africans, and 18th century American colonists. Heck, probably more just than that last group, because the worst oppression they faced was a bit more taxes. (And I still think that their cause was just enough to be worth breaking free of the US through violent means.)

Every one of those groups used tactics that would be called terrorism today. And history looks back on them kindly. The smart thing to do is to be on the right side of history today, not wait until it is history. And the bare minimum you can do here is acknowledge that while it might be better if fewer innocent people were killed as a result of their actions, Hamas are, on the whole, the good guys in this scenario. And that, at worst, every action Hamas takes is one caused by Israel's actions towards the Palestinian people.
