I disagree with the idea that a character being fleshed out and complicated means the author is projecting themselves into the story like you're claiming.
I don't think it matter to discuss it anymore either way.
No.
It's actually true.
In late 2011, GRRM was promoting a Dance with Dragons on his book tour in Europe. He did a session a public library somewhere in Germany with both fans and reporters and took questions from both.
A fan actually asked him which character he saw the most of himself in and GRRM basically laughed and told the fan that he knew exactly who it was but thanks for asking. He went to talk about his childhood in New Jersey, the family never having enough money and how isolated he felt rarely traveling outside the confined his local community. He lamented that he wasn't much more physically attractive a young man than he is now and found his escape in comic books, horror, and scifi. He was a geek and didn't try to be anything else and he was picked on by other teen boys. He came to resent if not hate the athletic, good looking, guys that always seemed to have everything go their way and got the best looking girls and just the whole way teenage society worked in America.
Said writing Tyrion was the easiest for him but writing Theon, Jon, Jamie, and Rob was the most fun because through those characters he exacted revenge on the boys that made fun of him. He would make them suffer and take their amazing lives and ruin them. Alpha males losing the abilities and looks and "other things" that made them the men they were. And Jon of course would never find any real joy in his life.
So there is some basis for the whole argument.
/yeah, I totally just made that up
