Your comments are shallow because you just continue to assert the idea are bad with no reasoning. You also clearly don't know your protestant history: Martin Luther did basically just whine about the Pope. He was thoroughly a reformer that wanted to see the Catholic church changed; he did not condone "Lutheranism" as a separatist movement.
The reasoning is historical precedent. If something doesn't work out the first time you try it, why would you do it again.
We are talking about at least 10 pages worth of proposed reforms. Do you have a specific one you would like to discuss? I'm not particularly interested in writing a 10 page essay in an hn comment about why i think all the proposed reforms are stupid.
