Now I am not a member of the Screenwriter's Union and Screenwriters have not been particularily supportive of me. Yes, this is true, and it is also true that I am for them and their strike.
I think the term writer covers us all, and is the most general and least defensive term. It's the one I use.
What people seem to be asking me/us when they ask us what we do and we answer writer is "Are you published?" "Have you sold?" As if that will legitimitze our activity.
Trouble is a writer has to write even if one never does get published, or published for money, big money. I also think that writers have a more difficult time with all this because an artists' work is more a product. An artist can show a drawing or a painting and it says what it says to the viewer without words, while words can help a reader see in their mind characters and the world of the novel. My writing partner on his memoir, Wes Bryan, got me into calling musicians, singers, anyone in the arts an "artist" but to me it still means painter.
