Why should you feel that way? I've never heard a businessman say "I'm disturbed that artists think they're engaged in a business." There's nothing more noble about one profession or the other, every path has its place. It's not even worth getting into a discussion about "what is art" here (although I do believe that a creation that comes from your soul and expresses something about who you are and how you see the world to be art, no matter what your medium). Even if your definition of art doesn't include what someone else calls their art, there is no reason at all to be bothered by that. They're not taking anything away from what you do, so focus on loving what you make and don't worry about how others refer to themselves.
