Yes, Christians did that 1500 years ago.
Muslims killed Sabeen Mahmud yesterday.
Pray forgive me if I see the Muslims as a significantly larger threat.
There are countless more recent examples I could have written about. However, Hypatia is in my opinion more relevant. Before 400AD or so, Roman and Greek society was based around classical foundations of rationalism and philosophy. Yes they worshipped gods, but there was tolerance for the worship of many different gods, and by extension tolerance for fundamentally different world-views. Classical civilization created great art, great philosophy, great mathematics, great architecture. We owe our systems of laws, of money, of art/drama to classical Greco-Roman civilization. And the fact that Greco-Roman civilization had flaws (e.g. slavery) does not change the greatness of what they accomplished.
In the early-mid 300AD's Constantine came to power as emperor of the Roman empire. He made Christianity the state religion of the empire. Christianity spread like wildfire, snuffing out anything that opposed it. The instance I referred to earlier, Hypatia's murder, is commonly thought of as the end of the Classical Era. In Hypatia's school, it is possible that astronomers theorized that Earth travelled around the Sun. If an astronomer had thought this, the idea would have been discussed and possibly accepted. In the new christian world, to suggest an such an idea would be blasphemy and would result in the suggester being executed in some gruesome manner.
The adoption of Christianity in as the state religion in Europe led to what is commonly known as the Dark Ages, a period of about 1000 years in which European civilization stagnated. Progress in the arts, in knowledge of the world (what we would call science), in philosophy largely came to a halt. Europeans largely forgot how to build great buildings. This era is thought to have begun to come to an end when European intellectuals began re-discovering Greco-Roman rationalism during the Renaissance, and is exemplified in Florence, when the architect Filippo Brunelleschi re-discovered Roman dome building techniques in order to build il Duomo.
When I see these stone-age islamic fanatics trying to hack away at the edifice of modernity, I cannot help but thinking about what christianity did to European civilization during the Dark Ages. I also cannot help thinking of those in America who so resemble these stone-age fanatics, the christian dominionists and those who can best be described as the American taliban. If you think it is only muslims who are capable of fanaticism, you are fooling your self.
