There is so much debate going on about whether the guy who shot Rep. Giffords was influenced by communication such as Sarah Palin’s crosshairs, or was just a lone nut case.
Friends, IT DOESN’T MATTER!
Even a lone nut case is affected by environmental factors, and the communicational environment in the U.S.A. has been poisoned for a good 20 years now.
It’s in the air, and anyone can feel it.
When you live away and you come for a visit, you feel it so thick you can cut it with a dull plastic end of a lifelike plastic Kalatchnikoff barrel.
When it’s in the air, the nut cases will pick it up.
So will others.
Who cares if Loughner read Palin’s (or other extremists’) site or not? These sites didn’t cause the shooting, they created the atmosphere that helped someone decide that it was OK to shoot.
