Ummmm... NO. Munch was a hippie, a conscientious objector, and most importantly, a member of the well-integrated Baltimore Homicide squad who quite obviously thought the world of most of his coworkers, including those of different races. Munch has got plenty of flaws (Alyssa Dyer's roommate!), but dude, get them right. Lame-ass bigoted comments just aren't in character for him.
Then again, the fucknuts writing SVU think he grew up in New York City... (all together now) NEW YORK CITY?! Get a rope!!
