I have some thoughts on this.
Coming from a former alt-righter and former cult member who is still deradicalizing.
This is gonna be long.
Thread time.
This is de-radicalization going terribly wrong. This is keeping the tactics you learned in a hate group, but turning them on others. This is not unlearning. This is changing targets.
This is weaponizing what you learned to harm those who personally don't back you.
Look, I could sit here and break down my life. Break down the threats I've faced. Break down the ways I learned to find people IRL. Break down why I endorse being anon if you need to. Break down why this behavior is wrong.
But you know what? Screw that. Others covered that.
What I am going to say, is that it is a tactic of cults to teach you that you are the bravest, the strongest, the best, because of your membership in a group and your goals. That you are better than the masses. Above them. You are superior. "The Alpha", as Amy says.
It teaches you to be belligerent. Aggressive. If they're not with you, they're against you. It teaches you to center yourself. Everyone else doesn't matter. They don't understand. They aren't on the same level as you.
It's a delusion.
