Not only are you misrepresenting what Pao did and didn't do at Reddit, your analogy is poor too. The subreddits in question were utter trash, maybe even illegal in how they targeted people, and a very poor representation of what Reddit is.
I'd disagree, the fatpeoplehate subreddit is basically the same thing as /r/trashy /r/cringeanarchy and other other popular subreddits that are regular fixtures on the popular page.
It's a thoroughly unpleasant website.
