You're subtly misattributing me though. "Convincing someone" is a superset which contains intentional manipulation of the information someone is exposed to but also lots of other things.

As you said, how you do it matters a lot.

You've also gone and (IIUC) equated the general biases of an outlet with propaganda which I certainly wouldn't agree with. They're similar, and the former can certainly morph into the latter, but they aren't the same thing.
