They are groomed to be that way, and even when wrong, and get bruised up, they have a cheering section, that tells them they were right.
It reminds me of a guy I met in fla. and every time I saw him he was bruised and cut up, due to family. I finally asked, 'how many fights do you think you've lost?', and without a beat, he came back with, 'All of um'.
Some just never learn.
