Writers Beliefs

I do believe that the writer does not believe in everything that he/she writes. Some of the time they write to reflect a certain aspect of one the the characters. But on the flip side some of the time they do express their thoughts and beliefs through the characters as well. It is really hard to judge because we do not know the writers themselves, and we do not know what their like. Cuz alot of the time some of the things they are deliberatley a taboo just to stir the pot a little. So overall i dont think anyone can really tell whether or not the writers believe it is what they're writing.
