It’s quite a rabbithole. My “favorite” is the fearmongering around reactor waste products. People resist nuclear because we “need to store the waste”, even though we can reprocess it back into fissable fuel. But also we “can’t” do that, because that process can potentially be hijacked to produce nuclear materiel.

Both are valid concerns, but it shouldn’t be an impossible problem to solve. Especially these days, knowing how destructive some of our other common fuel sources are.
