You're absolutely right.
Fate Stay Night threads do not belong on the Anime and Manga board because it originates from a visual novel. By association Clannad, EF, and School Days threads do not belong here.
And Full Metal Panic threads do not belong on the Anime and Manga board because it also comes in the form of a light novel. By association Haruhi and Zero No Tsukaima threads do not belong here.
And while we're at it since Akagi is based on Mahjong, and Mahjong is not an anime or manga, those threads don't belong here. And since they made a live action movie out of Dragon Ball Z and Death Note, I hereby declare those irrelevant to this boards interests. gb2/tv/
