I think this article is a little too overzealous with trying to simplify a topic like beliefs and ideas.

A lot of it also sounds like common sense to me, the people capable of grasping this:

> Be careful what beliefs you let become part of your identity.

Are quite capable of adjusting themselves.

Everything else falls into either Ego, or people being self-(un)aware, and for the latter - you can only change "their" belief system if they themselves are willing to change.
