Great, but this isn't that. This is the fediverse where the existence of unique subcultures are promoted and celebrated.
The only thing happening here is that redditors who are coming over to fedi for the first time are having a culture shock when they're exposed to anything outside of "thanks for the gold gentlesir", "rip my inbox" and nasally snorting about some logical fallacy in a basic conversation. Which is funny because the rest of the internet has always viewed reddit culture as a freakish attempt to act like being Sheldon Cooper from Big Bang is a good thing. Bazinga!
