Show solidarity with people, not with states.

Yes, a large portion of Israelis supports the ongoing genocide. That doesn't mean killing any inhabitant of Israel is good. Combatants actively contribute, and they're fair game, but not civilians. You know neither the opinions of the now dead, nor why they held them. The people there are, to an extent, victims to their system, which makes them think what they do. The ruling ideas are the ideas of the ruling class.

I understand why Hamas made the attacks, but that doesn't mean I think they were good. Civilian casualties are always bad, no matter if in Israel, Palestine, Ukraine or Russia.
