This isn't a turn for Jordan Peterson. It's who he's always been, and a lot of people tried to warn you about it 5+ years ago. The only new thing is that he's not trying to dress it up in fake objectivity anymore.
Have you spent any time wondering how those people knew this was coming years ago, but you didn't see it?
Nope. For the same reason I know many people who voted for Trump, and then didn't after four years of him.
They just didn't care to spend more brainpower on the issue than they already had. Most people have better things to do than be the most well-informed voter or investigate the history of the people they see on YouTube.
