I do wonder how much hate speech, especially in the early 4chan years, was a deliberate shield against those _not_ targeted by such speech but still cannot ignore it. Think of white people who would post a "how dare you" rant when they see the n-word or male feminists. It's a way to keep out the moral guardians and cut down on behavior I like to call "dogshitting." Unlike sea-lioning and its "per our previous conversation…" off-topic nature, dogshitters nominally address the parent post… with nitpicks irrelevant to the thread's larger topic.
