Your insult was too clever…probably much better than they could come up with. Thus you are chalak.
You can’t win. Can’t beat em…join em. Pretend that you’re just as obtuse as them…and make similar tactless comments in a similar obtuse manner. If they get mad…play obtuse…and say..“Oh you know me…seedhi saadhi that I am…I guess I don’t even realize what I’m saying is offensive to others.”
