BGMaxie, I sincerely feel that you are simply going out of your way to be an annoyance to many people. Your opinion is not shared by a large part of the community as well as not popular in the industry to begin with. A lot of stories in television are taken from books or other sources. Manga happens to be quite big and far more appealing to be put into animation. To look down on manga as a source of story material for anime is fairly pointless.
Do you wish to know why? Well, if it has not yet occurred to you I could tell you this: Stories no matter if they are BOOK, FILM, MANGA or ANIME are always written by people. Succesful mangaka's have written appealing stories the only hurdle in adapting it into anime is the adaption process itself. The people writing an original anime have to proof themselves during the animes run, the chance that the anime would turn out badly is significantly higher than of a popular anime would be adapted. Not to mention, the additional writer that would be needed would provide an extra cost-post and the anime has less guarantee of financial success since it cannot tap into an existing fanbase. Manga adaptions can do this even if they 'suck'. Hence they are saver.
I also feel entitled to say that what you stated is an insult to mangaka's, who often manage to have a story told in a more satisfying way than they can manage to do in the adaptions, simply because the script adapters ( writers) cannot achieve the same level of storytelling as the mangaka.
