When I was a liberal, I was really just extremely apolitical and liberal by default. So I don't know if I so much as fell for regime change propaganda as much as understood the world as it was told to me by people I trusted. Like, there wasn't really anything else that I could've believed without putting in the kind of effort that I didn't have the ability to yet, since I had no ability to understand politics. When I saw "regime change propaganda", or, "the news," shared by friends from big American news sources (because I didn't really read the news, just got news from friends) I just sort of trusted it by default because my natural state was not to distrust CNN, etc. It's not like I knew any better, I didn't really know anything, I probably couldn't have even named any non-MSM news source. So I think it was just sort of default like, these are the trustworthy news sources, they're not going to lie, or if they do, it's an honest mistake.

And then I guess once I started to move left, I think the problem with still falling for regime change and other propaganda was that, I guess its like, once I recognized how untrustworthy new sources like CNN could be, well really any news source could be just as untrustworthy. So it took a while to get from generally trusting CNN to now finding news sources that I can trust, and it was a long middle period of being highly distrustful of any news source, MSM or not. And to find news sources I could trust, I first had to build up a political understanding. And for the most part I did that alone because I had no leftist friends or no leftists in my life IRL. So I think that's another problem - fully recognizing the extent of US propaganda and fighting it really puts you at a distance from many of your friends and family. So I think there's a hesitation, or maybe a slowness, in leftists fully recognizing how much of their lives are shaped by propaganda, since it goes against most of what you're taught and its very isolating, especially with the state of the left in the US, especially pre-2015. Which is why sites like this are good!

So, to sum up I suppose, to not fall victim to regime change propaganda, one would need a political understanding that most Americans do not have and is not taught to them, so the two choices are generally trust MSM with all it's flaws (that you might recognize but at the same time say it's better than other sources). Or become highly distrustful of all news sources since you recognize the flaws and lies of MSM, but you haven't developed any political understanding to fight the propaganda, or recognize a trustworthy news source - which creates a very nihilistic. And then to recognize US propaganda can make someone who has grown up with it their whole life feel like they're heading into tin foil hat conspiracy territory, and also make them feel increasingly at odds with friends and family.
