It'd be nice if You provided us the sources of information, especially that one could, esp. when it comes to reformation-times popes, expect a high level of bias, just as one of yourself ("Popes throughout the ages have always faced a pressing problem. namely "how the hell can I get the cash to pay for my lavish lifestyle and huge retinue of totty?". For a considerably large part of the history of Catholicism, the solution proved to be in prostitution", "fornications of the average Pope")
Still, much of the information seems to be true. Even catholic encyclopedia condemns some of these. Worth to remember that many of these achieved their position unruly and were deposed one way or another. They did not represent the church as much as their own or their family's ambition.
When it comes to Sabinian, however, He didn't close the granaries. He just refused to give the grain completely for free.
When it comes to Urban II, You seem to mae Him responsible for hostility between Christian and Muslim world. That is nonsense.
"Medieval holocaust" - blah

I'm a Roman Catholic, and I'm an avid and devout follower of the papal throne! I believe in infallibility! But the thing is, the pope is only infallible when he is speaking (making a proclamation) on moral issues, and he is united with the bishops!
I have admired all the popes and Catholicism throughout the history of the Church. The Church may not look as though the perfect place, does not claim to be, and is not! It is designed to lead to a more perfect union with God on earth! The Church as a whole has never lost sight of this goal!
