This is the new item in the news where a person can state his or her opinion on something. As I wrote earlier, it took CBS quite a while to give time for any liberal views and the feature is still very wingnut-tilted. Take a current example where the father of one of the boys killed in the Columbine massacres opined this:
This country is in a moral free-fall. For over two generations, the public school system has taught in a moral vacuum, expelling God from the school and from the government, replacing him with evolution, where the strong kill the weak, without moral consequences and life has no inherent value.
We teach there are no absolutes, no right or wrong. And I assure you the murder of innocent children is always wrong, including by abortion. Abortion has diminished the value of children.
Nothing about the easy availability of guns which turn one angry teenager into the equivalent of a small nuclear bomb. I think guns are why the United States has so many more deaths from violence than the European countries. It's just easier to kill lots of people with a gun than with your bare hands or a knife. But discussing this is politically futile.
Still, I could notice that school massacres unrelated to terrorism are a largely North American phenomenon, and so the cause for them might have something to do with whatever differs between this continent and, say, Europe. This difference is not in the availability of abortion or the teaching of evolution in schools. The difference is in the relative ease of getting armed to the teeth.
