Another poster has linked you to his video on this topic. Yes, he said some very stupid things to provoke discussions and reactions, and the whole thing was both immature and misguided. But shouldn’t you be able to say “I did some very stupid things and will do better in the future”?
If he did something similar more recently, I’d be with you - tar and feather him, and exclude him from the community. But he hasn’t (afaik). Mistakes shouldn’t brand you forever, as long as you’re honestly doing better and working against those mistakes.
