Sorry for the belated reply. Of course you can be utterly depraved and straight. Most of the artists I know aren’t depraved, or at least haven’t displayed behavior that might make me think they were. The problem seems to be that most of the famous artists seem depraved, because so many of them are depraved. Still, for every “famous” artist there are thousands of real artists, working hard, living decent, non-depraved lives.
