To learn that we went to war with North Korea because it's communist? No shit. We also did that with Russia, China, Vietnam and a good fraction of current NATO members, trade partners and allies.

Elites? Most Americans have unfavourable views of communism [1].
But you didn't say communism. You said socialism. And it's a bit ridiculous to argue (a) North Korea is run as a socialist economy or (b) that we have a beef with Pyongyang, today, because of how it runs its economy.
I don't have a beef in this discussion but I just want to point out that if you want to quote a source, then quoting Victims of Communism may not be your best move. They label all WW2 Nazi casualties by the Soviets as "victims of communism" so not exactly an objective and truthful source.
