If it makes me uncomfortable to see intolerance like that in my friends and family, when I see it in the gaming community it makes me sad. Even if the bile and vitriol launched by some segments of the gaming community against anything that deviates from a "traditional" roleplaying game is from a very small, vocal, abrasive minority - it still serves to drive wedges between people who, ostensibly, all want the same thing. To play some games, without someone trying to judge whether or not it meets some mythical standard of "roleplaying".
Disagreements are fine, and debate is essential in helping us refine things that we enjoy or don't enjoy about gaming - and even discover new (or even old) points of view. But for fuck's sake, some people just need to stop trying to exclude people because they don't roll their dice a certain way. Who knows, maybe you might learn something from the "swine".
