New York Knicks owner James Dolan – also the president and CEO of Cablevision – goes full Dick Montfort on a longtime fan who questioned his competence in an email:
Mr Bierman
You are a sad person. Why would anybody write such a hateful letter. I am.just guessing but ill bet your life is a mess and you are a hateful mess. What have you done that anyone would consider positive or nice. I am betting nothing. In fact ill bet you are negative force in everyone who comes in contact with you. You most likely have made your family miserable. Alcoholic maybe. I just celebrated my 21 year anniversary of sobriety. You should try it. Maybe it will help you become a person that folks would like to have around. In the mean while start rooting.for the Nets because the Knicks dont want you.
Respectfully
James Dolan

Jim Dolan is a billionaire because his dad Charles founded HBO and Cablevision. Jim once fired a bunch of people at a company party — the annual Christmas party. His dearth of kindness was well-known on Long Island, the place from where I came to Denver.
