The same is true for non-Wikipedia sources too, right? If you learn about political topics from, say, a newspaper article, you will not be able to tell if you're looking at a propaganda piece because the newspaper is exactly where you get your prior knowledge.

I think there's a difference: you know that newspaper won't offer you an objective prior knowledge. But with Wikipedia, too many people have such assumption.
