Just to make the point for the third time, people aren't even discussing the video that was actually shown in the class. Apparently, it doesn't matter what actually took place. What is important is what you perceive to have taken place.
We don't know exactly what was shown to the class. The class saw maybe three minutes of video; the entire discussion runs an hour, much of which is Peterson monologuing and mithering. But this was already discussed on this same page, as you can see if you scroll back up.
In the absence of video evidence, we are discussing whether Jordan Peterson is, ceteris paribus, useful material for understanding trans issues. Posters have attached many links demonstrating that he is not, due to a history of transphobia and bad-faith arguing. The video under discussion does not disprove them, and even if it did, the man's history on the issue does not inspire any confidence. Peterson, like Milo, is a known quantity. When Milo appeared on Bill Maher a while back, played down the vilest aspects of his extremism, and in doing so charmed the host, that did not suddenly excuse his prior actions or constitute a change in behavior. Peterson may have left out some of his more reprehensible comments for this video, but he hasn't changed.
