We can’t shove the blame for one person’s actions onto another individual. The culture of the US could be blamed but not specifically a Sarah Palin.
However, in one blog it was pointed out that the Sarah Palins of the world and her supporters are usually the people who rail against video games and Hollywood because of the violence and the effect it might have on young people. But when they make inflammatory statements and put crosshairs on maps, they deny that that has any influence.
Not sure if they can have it both ways. (Just as the other side can’t say that video games have no influence but crosshairs on a map do.)
It’s always fun when inconsistencies appear.
