Cute. And how pertinent! Especially considering I'm using words to illustrate my views, and you, well, don't. I really couldn't care less about casting, as long as whoever is hired does a good job in a fine story. Imagine the party they'd have over at the IMDB message boards (where tourette-like exclamations like "retard" or "moron" constitute valid posts) if they had put Cumberbatch in brownface.
