They were being paid for their performance. The management have their rights also. Protest all you want, just don't expect me to automatically be a part of it through my patronage at the mall.

Was at a 5 act music benefit recently where the band leader (same city) did a anti-bush tirade at the end of their. The crowd had to be well over half left-leaning but the hush that fell over the crownd also resulted in him not selling one CD.

The average intelligent audience does not want political reflections cast on their entertainment.

Rent a hall or find a street corner and protest all you want. That allows choice.
