It was NOT paid for with yours nor my taxes nor anyone else's tax money. The concert was put on by the StartUp RockOn concert outfit and sponsored by several large corps. The guy was not THROWN off the stage. After about 20 minutes of repeating his anti-war, anti-Obama, the audience started booing and leaving the hall. The promoter went ouot to tell him to move on to another song. He refused and continued for another 10 minutes and then his mike was cut off and then the lights were turned off and security escorted him off the stage and away from the hall. Of course, you won't believe that but you can look it up for yourself. There is no need to apologize.
