Just because other people like things that you don't, does not mean you are morally superior to them. And even if it did, it still doesn't give you the right to degrade them is such a way. Call of Duty players are not evil, sexist homophobes, they're just people who happen to like the gameplay. Yes, some of them are the kind of morally reprehensible people nerd culture has made them out to be. But I also know lots of guys who like Call of Duty, and who are perfectly nice people.
Yes, I get that the Anti-Thinker is meant to be parody, but here's the thing. While the exaggerated CoD fan is a sexist asshole, the (maybe) exaggerated Nintendo fan wants more creativity. If you're going to take the South Park approach of making people look like idiots, at least have the decency to make both sides equally idiotic.
It'd be really easy too. For instance, make the retrogamer demand nothing but old-school platformers while dismissing experimental indie stuff because they're not "games". It'd still be in bad taste, but at least it wouldn't be as horribly biased.
Look, I really like your analytical stuff, even if I don't always agree with you. But what you're doing here is taking cheap shots at people who can't fight back. Essentially, you're bullying.
