Lost amidst the media coverage of the VT shooter is this grim report from Turkey about an attack on a Christian publishing house, in which three people were tied up and had their throats cut. While Turkey is "officially" secular, it is only "secular" in that it is not an overt Islamist theocracy; sociopolitically, it may as well be. Ultra-right-wing nationalism is rampant, and these killings were carried out by just such a group of Islamist extremists.
So here we have another case of people dying because of differences in belief about a nonexistent invisible man in the sky. And that's it. It is sobering and disgraceful that in the 21st century, people still kill other people because of what they believe about their god. If the human race does not grow up sooner rather than later, reject these ancient superstitions, and embrace reason and reality, civilization as we know it will not make it. Deal with this: THERE. IS. NO. GOD. Full stop. So put down your guns and your knives and your bombs and learn to live with each other.
