Love this! Is the goal to really change attitudes and improve, or just to feel superior and 'win'? If it's the latter then continue the call out, if it's the former then a different approach is needed.

Has being called out ever made you want to change your behavior? Or did it further entrench you in your previous attitudes/beliefes/ways of being? Nothing is more effective at changing my mind and practices than some friend taking me by the hand and explaining their perspective to me.
