How idiotic would it be to debate the color of Smurfs? It is a pretty fucking stupid waste of time given that they are fictional to begin with. If you add on top of that that the "literature" all indicates that they are blue it makes even more absurd. It is this type of silly frivolous nonsense that comes to mind when I read pieces like "‘Noah’ film sparks debate over one of the world’s oldest and most beloved stories." Seriously?! What is there to debate? It's a fictional story and even if you want to look at it in terms of metaphors or "deeper meaning" it is still horrible crap. Noah is a bad drunk (Genesis 9:21-24) and God is a genocidal asshole. Drowning a whole planet you created because you don't think it turned out quite they way you wanted is pretty fucking twisted.
I'd rather debate Smurfs. They are at least cute and don't hurt anyone, metaphorically or otherwise.
