I am sure a lot of us have met fans like that; I personally have met a few. Like everything that gets stereotyped, it gives "normal ish" fans a bad image. People tend to perceive every anime fan the same, as cosplaying pokemon ( whatever your generic choice of anime) watching anime nuts (Generally anyways)

I dont go to anime conventions. I think 98% of cosplay is terrible (Only if the chick is hot, or if they can pull off the character) I don't use Japanese words in my sentences. I don't hang out with others to watch anime. I just like watching anime.

If you do stuff like that then, good for you. I don't like being grouped together as a single entity. Most times I mention anime here, I get the same retarded look from people.
