Ron Olesko said, in part:

I also just read that she apparently has been making the remark abotu Micheal Moore at each of her shows since the film opened. So why did it suddenly become an issue at the Aladdin?   Why haven't other audiences reacted this way? Why wasn't it reported?

If she's been saying those things (with which I agree, remember) regularly in previous appearances, then the Aladdin reasonably should have known the likelihood, and I would then withdraw at least the strength of my criticism in posts above. If (as several posters have mentioned) Aladdin knew (or should have known) this likelihood and didn't like the possibility, it was indeed up to them to prohibit it contractually.   

As to "firing" her, I believe I read that it was to be a single appearance in any case. Not letting her even go to her room before leaving the premises seems pretty harsh in any case.

I still question her judgment in making the statements in that context, but that's not too big a deal.
