I can also point out that Mary/Gary sues are also spawns of new writers. Its hard to bash someone who is just starting out, you have to give those people a break. I'm pretty sure we were all guilty of sues in the very beginning. I know there are the rare few who write sues just because they like writing sues. But there are the new writers who are just learning, and will be just like the rest of us when we read our old work and cringe at the thought of how we used to write then get proud on how much we've improved .
