My take is that it's because a certain percentage of the population has been systematically manipulated to think and act against what's in their own best interest. This isn't the only topic it applies to. They get their 'news' from those who pedal in fear, blame, anger and enemy. And then they coalesce in to "sides." Being part of a group is really important for some. It gives them something to fight against. People literally died because they were told that Covid was a hoax. And they believed it. So when death isn't a deterrent all bets are off.
