Isn’t there a Vonnegut quote about artists not mattering when faced with state power?

Found it:

Every respectable artist in this country was against the war. It was like a laser beam. We were all aimed in the same direction. The power of this weapon turned out to be that of a custard pie dropped from a stepladder six feet high

I always think about Norm Macdonald saying "oh, you know, everyone says comedy is important, comedy takes down bad people. but, you know, in weimar germany, nazi germany, there were politcal cartoons saying hitler was bad and the nazis were bad, and it didn't acheive a whole lot."
