If this is an accurate description of the belief system it sounds like it's adherents are extremely anti-social individualists who are a danger to everyone around them. What are viewers supposed to take away from this?

This really sounds like the fascist belief that action for it's own sake is better than thought, and that war is a goal unto itself. It just lacks the "revitalizing the nation" component, as it seems to stop at "I just like breaking stuff."

Also the narrator walks right up to the "Blaming Jewish people for their own murder during the Holocaust" line, if not actually crossing it. Generally speaking, people who are anywhere near that line do not make good friends, allies, or comrades.

There's also the anti-civ stuff. Anti-civ is bad because it means me and pretty much everyone I love would die in agony one way or another. I get that the speaker has apparently decided that's already happened and any attempt to preserve your life or anticipate a desirable future is... bad? But that pretty irrevocably puts me at cross purposes with them.

I don't find this ideology interesting at all and I don't see any reason to consider it or investigate it, so I'm really asking if there's any reason to tolerate the presence of anyone claiming this belief system, or if they should be turned away immediately?
