I told you to get off my case.

My comment was about the concertina, which IMO is a boring instrument, not concertina players. Concertina players weren't mentioned, so it is not offensive to concertina players, except idiots who have themselves chosen to make it about concertina players.

Take your insecurities and hang-ups and look for another victim for your rudeness and aggressiveness. I don't roll over and die for anyone, especially notoriously argumentative players of boring instruments.

Got the message yet?
