America has become desensitized...there are several reasons for it.
That is all.
Meister, a friend and I were having this same discussion. We did list some of the reasons we believe might be causing this desensitizing.
I'm not buying it. Children throughout history have been witnesses to violence and death and even play rolled on the subject (cops n robbers cowboys and indians) yet only now do we have this problem.
Why don't the children that are first hand witnesses to these mass murders then go on to become murders themselves?
As a society when we witness something we can't explain we fear it and as a result react by trying to place blame where none exists in order to feel better about it.
