There is a very easy answer to this though. If I was a lib, I would say "Well Azov didn't attack Russia and kill their civilians." There was no big, flashy, inciting incident that triggered the Ukraine invasion, to see any nuance in it you already need to be aware of NATO imperialism. Hamas also explicitly seeks the destruction of the Zionist entity which (from what I know) cannot be said about Azov and Russia.

Condemning Hamas but not caring about Azov is not being inconsistent, both make sense if you look at the events in complete isolation. If you believe Ukraine and Russia just spawned into existence in February 2022 and the bigger country attacked the smaller one with no political context, or if you think Israel & Palestine peacefully coexisted until some crazy Muslims decided to massacre Israelis one day because Allah told them to.

There's also the fact that Hamas is the elected government of Palestine, while Azov is "just" a part of the Ukrainian military. You can talk about how deeply entrenched Nazi ideology within the Ukrainian government is a driving factor in keeping the war going, but Azov themselves aren't a major player in the war like Hamas is.

tl;dr I don't think this is a very good gotcha and I wouldn't try to use it to own the libs with facts & logic.
