I don't understand a lot of it either. Mostly it's reactionaries being butthurt that the rest of the Internet isn't reactionary, and I can't profess to have a solid understanding of the reactionary mind. I don't understand what's kept this going on so long apart from the fact that haters gonna hate, because the premises it's based on are completely fictitious.
Movie Bob had a good summary last month that i can try to find if you'd like (that he predictably got flamed and blacklisted for). Of course that was a month ago. Cracked has run a lot of good stuff too.
I think gaming is pretty much ruined forever as a respectable hobby after this. I mean, smurfing terrorist threats? Really?
