Bad artists?

I am responding to Skyla's post question: Is there really such thing as a bad artist or is a bad artist not actually an artist at all?
I don't think there are bad artists because everyone in the world likes different things. I might have the opinion that a specific artist has bad work, but that does not make them a bad artist because I know that someone else probably loved their work. Mass Moca is a good example. I go there and look at somethings and think" uck, i strongly dissaprove of this" but if it was dissaproved of by everyone, it wouldn't be there, so clearly someone thought it was good. I think that experience obviously helps improve art aesthetically. That just means that with more practice, more people will like your art, But i do not think that there are bad artists.
Question: If someone says they are not an artist, but we think of them as one, what does that make them?
