Those of us in the west tend to forget that much of what we see is a form of propaganda, whether by governments or businesses, or even a large number of people. When you keep this in mind, everything you see becomes an opinion and your mind can comfortably (or at least not emotionally/hurriedly) form your own opinion over time.
I agree that most messaging is propaganda, but that doesn't really counter the real pain that is being inflicted upon large populations of people by these government (and corporate) moves, and being cheered on by pretty large masses of people. The propaganda is like environmental pollution -- hard not to breathe it in. That said, I have no answer here..
I must agree, but I think the global public's awareness has been shocked into growth. I find the biggest problem with social media is actually user error. Unfortunately social media apps have become so complex that many have given up on curating their feeds. This is critical. If you can tune your social media to show you _interesting_ things, you can stay informed, possibly get good context, and not lose your mind.
