Social media is where most of the blatantly false propaganda lives. Getting all of your news from it makes you more susceptible to propaganda, not less. These are people who have nothing to form an opinion with except for what the loudest people around them are complaining about most. And propagandists are the loudest ones, complaining about made up bullshit.
Thing is, normalizing stupidity and shitiness doesn’t help anything either. It actively makes things worse. I don’t know what the actual answer is to improving things with that kind of person though. I just think pretending that being a shitbag is acceptable behavior ain’t it.
