I do agree with him about the whole "Gamergate" fiasco. It is criminal what has happened to women in the world of video games.

As for him, have you ever considered that all this "super confidence" is just an act? He may be insecure on a major level. These never ending sermons may be an attempt to attract admirers. To bolster his fragile ego.

To me, a secure, confidant person recognizes that their self worth is not reliant upon getting others to agree with them.

From Game of Thrones:

King Joffrey; "I am the king!!!"

Tywin Lannister; "Any man who must say ' I am the king' is no true king."
