I'm not a fan of generalizing but everyone defending these kind of disgusting games always has anime or Moe avatars and it's pretty fair to think it's probably because they feel like what they enjoy is being attacked.
There's a lot of racist attitudes towards products coming from Japan these days. I don't know what else to call someone judging avatars in that way, except saying that they're anti-Japanese culture.
It's not just NeoGAF. It's tons of sites on the internet, and it's a common thing for people to judge people in that way, and to put down anything from Japan.
