I think Monk as a class is pretty versatile when it comes to a race, just as in real world. As westerners we also study Chinese, Korean and Japanese martial arts without embracing their culture as a whole. When I was doing Karate, we used to call everything by it's original Japanese name too. It is not like the phylosophy is in coflict with our national morals or anything.
I play Undead Monk because I like the race and I wanted to heal on other class than a Priest. However when playing a Brewmaster, I play it with an image of crazy Apothecary drinking her Alchemy creations.
I am glad Monks can be almost every race. I have nothing against Pandaren as a race, but I just dislike like how dumb some of their animations look. Some may call it cute, I just find it dumb. It is the model and animations I don't like, same reason why I can't play any Worgen caster (Their casting animations are HORRIBLE).
