This is an interesting comment! He has been making the same speech for 30 years now, there is indeed a reason why it hit the nail in 2015, and not in 1995. In a way, one could say he became "lucky" that the culture war turned out like it did because it gave his discourse a case to be applied to. In a way, Peterson's philosophy was a solution waiting for a problem. When wokeness arose, both attracted each other like magnets. And he became famous.
Had wokeness never been a thing, we would have never heard of Jordan Peterson, and he'd still teach in Toronto to this day.
