New York Knicks fans are not happy with team owner James Dolan.

In fact, two brothers are now launching a website calling for Dolan to sell the team.

The reasons are many, the Knicks are 10 and 41 this season after hiring 'The Zen Master' Phil Jackson as General Manager and re-signing Carmelo Anthony to a long-term deal.

But the final straw came earlier this week when Dolan emailed a fan telling him to root for the cross-town rival Brooklyn Nets because the Knicks don't want him as a fan after the fan sent Dolan a letter detailing his disappointment with the team.

ESPN New York is reporting the same brothers behind the call for NY Jets former GM John Idzik's firing have created Knicks4sale.com, a multiplatform campaign that includes a Facebook and Twitter account.

Knicks4sale.com posted the final paragraph of Dolan's email response to the upset fan:

"...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." - James Dolan

The campaign is looking to raise $20,000 in donations for a billboard on 30th Street and Madison Avenue that will be seen from the Knicks' home arena Madison Square Garden.
