I think it's in L.A. where porn 'actors' have to legally register as such so as not to be charged with prostitution. So porn can be made to be an art that way.

Porn in many instances involves racist and sexist themes, with females being intensely despised. So it's art in the sense The Birth of a Nation is art, reshot multiple times under different circumstances and distributed online. And rectal prolapse for some of the bitches.
