Cool question, thank you!
I think the best way for a human to identify themselves is as an individual first and foremost. Whatever interests and characteristics they associate themselves with or which cultural milieu they are part of what is makes them a unique person. So if you enjoy painting and take the time to participate in the art you are a painter.
Reminds me a lil' of "Hunger Games" lol
