You need to seperate Christian Woodford the show man from CW the professional S&C.That bloke is an absolute dud and a loser.
Yes he is a lunatic and probably has a half dozen mental disorders. That he tried to end it all a few years back supports this.
As an S&C guy, his theory's, training methodology etc.. are that of a completely sane and rational man. I know a few people that have/are training with him. They said they were quite underwhelmed at the start as everything was so basic and they were expecting all the bells and whistles and newest and funkiest exercises which is not him. Keeps things very simple.
