Actually, Paddy, you're wrong. There is a legal distinction between free speech and hate speech, neither of which have much to do with this, actually.

In point of fact, Michelle Shocked was performing in a club(which is private property), and the owners (who, incidentally, paid her) can ask her to leave at any time for any (or no) reason. That doesn't happen very often, of course, because in a club, everyone works pretty hard to make sure that the patrons have a good time.

The bottom line is that the folks in this club paid money to enjoy themselves, and the performer stood up and said some things that were pretty much calculated to make them upset. And so it goes...
