Annoyed by the critics that suddenly feel betrayed by the series because they had convinced themselves the games weren't sexist even when it couldn't have been more obvious. People tried to tell them Bayonetta was misogynist as fuck but they were dismissed as "sex-negative" or whatever.
His sexist comments are about how she's depicted in the game. He gives an example of a scene in the game as his way of showing that women see each other as enemies. He created the character so that she's mostly nude when she's fighting because he wants to leer at women. The game is influenced by his misogyny.
She isn't sexual. She doesn't do anything sexual in 1 or 2 and the people that kept saying she was feminist are upset with 3 because she actually exhibits her sexuality in that game and it's a disaster. In 1 & 2 she was sexualized, which was a different thing as I explained already.
Just watch the Lingerie is not Armor video. It's all you need to understand why Bayonetta is sexist.

Skip to the 5 minute mark if you only want to watch the Bayonetta section. The video does use term sexuality in a negative context, but it means something different to how we've talked about it here.
We've talked about sexuality in a general sense, while the video focuses on a specific type of "sexuality".
