I have a theory on this.

Zuck got property in Hawaii, befriended surfers as he learned to foil-board over the years, then he got into training and fighting.

The guy figured out who he was and got friends for the first time in his life. 

He was a nerd who had stratospheric success at an unbelievably young age. His original concept was around rating people if they were attractive or not - that’s pretty thirsty. 

He comes out as libertarian, posts pictures of him in his MMA getup, and goes on Joe Rogan to unleash. Dresses like a hype boy with oversized T’s, chain, and shaggy hair. Sounds like someone just got some confidence, and doesn’t confidence stem in part from acceptance? 

He feels cool now.
