It doesn’t matter. I don’t care if he had Sarah Palin’s “in our sights” poster on the wall.
He alone is responsible for his actions, crazy or not.
What liberals do, in trying to attack conservatives, is create a huge responsibility gap. “I’m not responsible, Sarah Palin made me do it.”
Liberals are dangerous to our freedoms. They want to suppress free speech. They attempt to ostracise anyone not in agreement with them. This would be called hate speech if the same was done to any demographic they pandered to. Never turn your back on a liberal.
