"In a Reddit thread under the title “Every Man Is Responsible For His Own Soul” [sic], Mr Wong wrote: “I did not say ‘we won’t ban any subreddits ever’. I said that we don’t ban subreddits for being morally bad."
Mr. Wong, with all due respect (that's not much for the record). Horse. Fucking. Shit.
If you make a rule against X (and ban X-related subreddits) but not rules against Y and Z, you're making a moral statement that Y and Z are more acceptable than X. There's just no other coherent reading of those rules. If you're trying to make a community where bestiality and racism are considered morally better than leaked celebrity nudes, that's fine - it's your site, but have the spine to fucking own it.
