If the Aladdin hotel, or any other establishment, doesn't like what a performer says/does on stage, they are of course within their rights to ask that performer to leave, never come back, avoid hitting their ass with the door on the way out.

But...

If I were at a show and some twit onstage started babbling about the wonders of Dubya, and urging us all to Tivo the O'Reilly Factor, and I "tore down concert posters" and "tossed cocktails into the air", wouldn't it be _my_ ass out the door?
