FWIW AJ you may not know everything about the situation. PVN (mayo) is an anarchocapitalist whose postions can be summed up as "There's no government like no government." Propertarian is a big government socialist type. Being that they are such polar opposites they tend to debate often. Here's propertarian's avatar-
Now I can't read PVN's mind but I'd bet that a lot of this just has to do with having fun with his opponents avatar, who apparently is someone that PVN dislikes a lot (who hates biggio, I'm a cards fan and even I like him). I would be shocked if propertarian's reaction wasn't laughing about it, and even more shocked if he was appalled about it.
As for the second one, Iron's avy was formerly martin sheen, and really I see even less wrong with it then the biggio one. If Iron took PVN's avatar seriously as some kind of attack then well I'm going to be forced to post this picture:
