I'm glad that this topic has opened up a bit of discussion here. I'm still seeing a lot of people confusing the ever-present use of racism in video game communities with the actual push by white supremacist organizations utilizing that racism/bigotry as an in to their ideology, but hopefully a few are opening their eyes to what's happening in gaming.
I want to reiterate, I think this is still a niche movement, but it's really starting to infiltrate into all aspects of social gaming, especially on the internet. I'm going to agree that the internet is the root cause for all of this spread of white nationalism, but it's just the starting point. As I said earlier, it's getting into things everywhere and gamers are being used as soldiers in their war of attrition.
I don't know if this topic has much steam left in it, but I updated the OP with a few of the links on the last page because I thought they were pretty great and very relevant. Thanks to everyone who's contributed here, and to the other people asking questions, I think that's fine as long as you come in with an open mind. If you're open to the answers people send back your way and willing to logically process the information provided, it can be helpful in refining the overall picture presented here. However, I'm also aware that there are certain forces that want to make this all seem like hyperbolic nonsense because they thrive on the ignorance of those they seek to turn to their side. Luckily, that stuff doesn't really work as well on Neogaf.
Just to clarify myself, I'm not saying there isn't ANY quality control, just that the pace of the industry has made for very little of it.
