Buddhism

I recommend you watching this: https://youtu.be/Kc3GHWIprWU

It is an interview with a former neo-nazi who explains how he got into that, and how it works exactly as a cult. Nothing to do with Buddhism at least in a direct way but very interesting. If you can have some compassion with him, you may also have compassion with the people who are still in the cult and all their world is hate.

In the end it is all rooted in ignorance and the same to some extent can be also applied to us, our ideologies, our beliefs and so forth.
