Probably his unending hatred for that match Kenny had with that 9 year old girl that people only remember becuase he keeps bringing it up.
Meanwhile Cornete was in a fucking gimmick battle royale. Not a match that was referred to as "the gimmick battle royale" after the fact, or the name given by the fans. It was booked to be named the gimmick battle royale. On the peak of Wrestling's most recent mainstream popularity.

Honesly though, it doesn't matter. He's a guy who works people for money, he's a carny which is fitting for his name. The whole point of his personalities and his views is because it draws people to his opinions and it gives him a rabid diehard fanbase and it sells.
His opinions are probably all real, but they're the kind of opinions that you have in the moment and forget about. He plays it up.
