I don't give two shits if you like animu, Japan, games, or what have you. That's great. I just don't like the people who are ELITIST PRICKS about it. Being knowledgeable about what you like or your hobbies if one thing, acting like you're better than everyone else because you watched some dumb poorly-translated fansub or a "raw," and now Dragonball or Naruto is "beneath you," is another.
This was a real-life occurance some years back, when I was working at a game shop. This uber-skinny dorky-looking guy in a bad Hawaiian shirt comes in and looks at the used anime tapes we have for sale. He asks me if I like anime, and then his eyes get all sharp as he asks me to name my favorites. "Uh...I like some older stuff, like Ranma 1/2, Captain Tylor, Riding Bean, etc." "Good," he says,
"because if you had said Dragonball Z or Sailor Moon, I would have stopped talking to you and left the store immediately."

What a fucking loser! The guy then gives me this spiel about this anime club he belongs to ("Anime X Atlanta," I think it was), and I make a mental note to never attend a meeting. Ever.
I also have a large amount of hate for "hardcore" fighting game players. I have never come across so many stuck-up nerds in my life. The attitudes from some of these video-snobs is unbelievable sometimes.
Oh another one is when someone post a picture of real girls and everyone is like "too thin, too fat, I wouldnt hit that" when in reality everyone who says that would probably drink their own cum to have sex with the chicks.
I think I know why this happens. With the internet, you have access to what is a virtually unlimited amount of pornographic and risque resources. These people have seen so many women that they have now become far, far too critical. That, or they're simply brainwashed by porn, and no woman with a gigantic rear-end and 34DD+ breasts will do anything for them. I think the people who always post "this chick has no ass" for a normal-looking woman and then follow it up with some abnormally-large set of buttocks are among the worst.
PD: TNW is the perfect example of an obnoxious japanophile. He hates everything American and shits on it every chance he gets. desu desu! fucking jackass. And the idiots on GAF who go to Japan and start threads about what to see but really are only interested in shit like akihabara and the nintendo museum.
TNW is a Japanophile. People who are just obsessed with anime, games, and other such shit are not. They're just pop-culture "okatu" freaks. But really, who cares? As long as I'm not being annoyed personally, it's not bothering me. It's when you try to gain attention that imma get pee-oh'd. See: tards like Applemilk and Maggybon.
