After confirmed that the racial statements made by Donald Stirling were him, Donald Stirling has been banned for life.
Though he has not been banned from owning the team. Only the board of governors can force a sale of the team. Stirling is banned from anything associated by the NBA. He can not attend games, practices, or any of the Clipper's facilities.
Personally I applaud this decision. Stirling has ever right to his own bigotry, and the NBA shouldn't allow such a man own a team in the NBA. Especially since, I believe 80% of the NBA is African American. This type of culture should not be allowed in the NBA especially from an owner of a team.
Though he still owns the team, and the Commissioner is pushing the Board of Governors to force the selling of the team.
