Nancy,I don't support this tax at all but I give Thousands of dollars every year to the arts, I volunteer with arts organizations and I buy art that I like. My not supporting this poorly thought out, poorly planned and poorly timed tax does not "deprive others of the nourishment that arts and culture brings." In reality the people that choose not to go and support the arts deprive themselves. I think it matters more to personal development and appreciation when people go and become a patron of the arts in their own way and on their own time. When someone is forced to do something that is good for them they tend to resent it.
In the end the primary reason why I don't support this is that it is about as poorly timed as President Obama's spending freeze. You don't take $ out of people's pockets in a recession. From either end.
