well, while it wasn't one of Penny Arcades funniest comics, I'd have to say that that is his oppinion, and not all that wrongly presented.
He's clearly stating that he doesn't understand it, and is turned off by it. but he doesn't bash furries, he just points out it's not his gig.
as with anything penny arcade does, they do it in an extreme way, saying "things we hate".
I find myself laughing at many other stereotypes they present and trash, so I don't feel it's right for me to get in an uproar about one just cause it includes me.
but that's only my two pennies.
