As a wise man has said, "If you are not breaking anything you are not doing anything, also."
The Stacker process is all about movement. It mirrors the world we live in. Hopefully we can stack good proof of work in the process.
Even when I gently or vehemently disagree with a Stacker I'm still reminding myself that that Stacker is a mirror of me. I'm thinking, "Why is my mirror so dirty, corrupt or rotten? Then the mirror says, "exactly, Grasshopper!"
