Well, MAGA is going to MAGA, right?
For all of those up in arms when we talk about Trumpism being a step toward fascism, this is actually a pretty good example of the doctrine. MAGA is about dumbing things down to a manicheistic view of the world, good vs. bad, us vs. them. No gradients, everything is black or white. This guy pushes the us vs. them to the extent that he is okay with risking these people's kids and doxxing them. What did the kids have to do with this? Nothing, but now they can be located and bullied, harassed, attacked. Most people would find this unfair and illegal, but for Trumpists, it's just an extension of the us vs. them.
Look at this guy being dumbfounded about his post being removed by Truth Social. In his mind, he is a hero. He is justified in everything he does, he is defending Trump and that's righteous vengeance. He cannot believe his own side would restrain him instead of praising him. Look at the guy attacking the FBI office in Cincinnati. Look at the Proud Boys, etc. They all feel their outrage is justified, that they are fighting the enemy for a good cause. The doctrine is about vilifying the other side to the point of making them look inhumane (starting to sound a lot like late 30s in Germany, isn't it?). Then, it's okay to do anything to them. Killing them, sending them to prison for no reason, putting their kids at risk, etc. It's okay right? They're "evil", "libs", "never Trumpers", it's okay to do anything to them because we are "justified", knights in shining armor making America great again... Oof...
