I have no interest in continuing a game if I blunder. When you do it stops becoming about creating a beautiful structure and just becomes another petty conflict with another human being. I have limitless contempt for those who do.
But not every bad move is a blunder, some "blunders" are great moves. That's when the creativity starts. My USCF and online rating are about the same, so I'm the first to admit my abilities are very limited. But I was playing a game a few years ago against someone a little over 200 points better than me. After several good moves, he was able to force me to lose a rook. Once he took the rook it looked hopeless, but he got a strange look on his face, one of not really shock, but confusion and worry.
After I saw his expression I took my time and tried to see what appeared to be something for him to worry about. I thought I had made a terrible move, losing a rook, and the game. But once I figured out the path now that the rook was gone, he resigned a few moves later. So I learned that people who are better than me are a lot more qualified to determine if a move I make is a blunder or not. I have a much deeper appreciation now for people who do not resign, because there is ALWAYS something I dont see.
Wow. I've seen shorter dissertations.
