The actually nuanced position is to be opposed to the bloodshed and race/religion-based tribalism happening with both the Israeli government AND Hamas, and to do more than just “tut tut” Israel’s recent activities in the West Bank and the virtual prison they’ve turned Gaza into.
Hamas is resisting Zionism, not Jews. They're pretty explicit about that.
So if you oppose race/religion-based tribalism you support Hamas, because they're the ones opposing it.
