I would say - same thing for me. If there is a logic and proof to alter My point of view there is no shame to accept this. If there is arrogance, blunt "I say this, this is enough to be Truth" stance there is no such option.It depends on the other person. If he/she is speaking in a respectful manner, in a "debate of equals", and the supossed mistake I did is presented with enough objectivity and logic, then I admit it without any problem.
But if the other user is talking to me "from above", or has no objectivity and logic ("this is my way of thinking and I am right because I'm right") I will not admit it. I want to share useful information/points of views, but I will not feed big egos or idiocy.
