Can you further elaborate! What do you say ?True, in my experience, where are you from? = what are you?
Like yesterday I was asking this guy with a clear accent where he was from and he replied, "Texas", so I let it go
Usually, when I've been asked that question I already know they're not sure what I am, and that "where" really means "what", so that's how I answer it or I give them a short monologue to avoid the usual stupid followup small talk questions.
