He apparently despises Jews.
Perhaps you admire people like that.
I did not think the Passion of the Christ was anything more than a snuff film. Gibson is a VERY angry man who is like his father in that regard. The anger comes out in his movies and now in this incident.
He may feel that he has gone beyond his father's bigotry..but he has not dealt with his own anger, rage, sarcasm and his own shame, whatever that might be,that comes out in this visciousness.
Having seen him on interviews, I am not surprised about this. This is one very angry arrogant man and when he is drunk, he is a very real danger.
His apology was more about "mel" being embarrassed, than a true apology to those he insulted.
