One point that almost always seems to be overlooked every time the Mary Sue issue comes up is that #*not* all original characters are Mary Sues. Although there are those who think OCs should be kept out of fanfic, it is possible and acceptable to write OCs into your stories without deifying them.
Too often an OC tends to slip into a Mary Sue mould, but if it's well written, I have no problems with an OC as a protagonist of a fic.
