You can just dismiss the person if it makes it easier for you to comprehend. Alot of times those people are insecure because they were bullied, or beaten or because an authority figure told them they were worthless. And you're on the receiving end of that angst. Which is unfortunate, obviously you don't deserve it. But we need to build a new world. Our current world is divided.

Your attitude creates only enemies. In a divided world, the best path forward is solidarity. So sometimes that means forgiving someone their flaws.

I'm a Pakistani American Muslim. I've been subject to racism in airports and elsewhere. I've been called Al Quaeda in school. I've had guys tell girls I was dating that I was going to kidnap them. I have been subject to numerous "random" checks in airports. My fiance is a Hispanic Christian and some of her family told her they weren't going to attend our wedding just because they couldn't support her marrying me. I could have just dismissed these people as racist and forgotten about it. But instead I invited them over to my parents house for dinner. And they changed their tune and now they are planning to attend.

You wouldn't be wrong for dismissing people. But in order to build a better world, we need to try to connect with people. Sometimes it means forgiving people who wronged us.

Idk enough about Hitlers story, but I do think most current day Nazis feel pushed into this belief system by a crumbling economy that doesn't value them. They feel insecure about being able to raise a family by the same standard their parents raised them. That fear and insecurity is coopted by MAGA in order to focus their ire towards some other. Oftentimes they lack access to other worldviews, either by reading books(due to a crumbling education system) or by meeting people(living in a homogeneous town).

This world was created intentionally by the elites to prevent progressivism/socialism from taking root. Most of these Nazis could have been Bernie Bros if they had a better education system or if they had been raised in towns that had minorities around.
