Why the hell does the internet use "Good sir" or some unusual defunct British response to respond to comments? It's not that its America. I don't care about that. But generally, it feels like a complete mockery of the person they are talking to.
No. I'm not mad. It makes little sense to me. If you want to refer to someone, just say 'sir' or 'madam' if you want to be polite. But generally, the messages created from these generally have a negative vibe like it''s condescending.
