Zell WAS angry. He was a guy who was committing political suicide out of principle and he was mad his party had abandon him. He made a LOT of sense though which made his anger rightous - he was speaking with all his heart and soul. It can't be easy going against the party you've been in and voted for all your life. Dang right he's angry.
Yup, righteous anger. .....Extraordinarily commendable.
