Debunking the myth of the old catholic church persecuting science and thus creating the terrible dark middle ages

Armarium Magnum is a blog by an atheist that knows about middle ages. He debunks the following:

The myth goes that the Greeks and Romans were wise and rational types who loved science and were on the brink of doing all kinds of marvellous things (inventing full-scale steam engines is one example that is usually, rather fancifully, invoked) until Christianity came along, banned all learning and rational thought and ushered in the Dark Ages. Then an iron-fisted theocracy, backed by a Gestapo-style Inquisition, prevented any science or questioning inquiry from happening until Leonardo da Vinci invented intelligence and the wondrous Renaissance saved us all from Medieval darkness.

Later he goes on saying

It's not hard to kick this nonsense to pieces, especially since the people presenting it know next to nothing about history and have simply picked this bullshit up from other websites and popular books and collapse as soon as you hit them with some hard evidence. I love to totally stump them by asking them to present me with the name of one - just one - scientist burned, persecuted or oppressed for their science in the Middle Ages. They always fail to come up with any. They usually try to crowbar Galileo back into the Middle Ages, which is amusing considering he was a contemporary of Descartes. When asked why they have failed to produce any such scientists given the Church was apparently so busily oppressing them, they often resort to claiming that the Evil Old Church did such a good job of oppression that everyone was too scared to practice science. By the time I produce a laundry list of Medieval scientists - like Albertus Magnus, Robert Grosseteste, Roger Bacon, John Peckham, Duns Scotus, Thomas Bradwardine, Walter Burley, William Heytesbury, Richard Swineshead, John Dumbleton, Richard of Wallingford, Nicholas Oresme, Jean Buridan and Nicholas of Cusa - and ask why these men were happily pursuing science in the Middle Ages without molestation from the Church, my opponents have usually run away to hide and scratch their heads in puzzlement at what just went wrong.

To read the argument in full detail instead of this advertisement that I am pasting here you should go to the actual post here, and maybe even read the book James Hannan Book: God's Philosphers: How the Medieval World laid the Foundations of Modern Science. (only 7 dollars in Amazon's Kindle)
