Based only on one meme on his Facebook page , I wonder if James Fields is on the autistic spectrum. People with Asperger’s are more subject to idee fixe. In most cases, these fixations are benign or not harmful. However, Instapundit and a couple Republican legislatures have promoted the notion that it’s fine to run over protesters who don’t share your views. If Fields were exposed to such arguments, he might have adopted them without truly understanding the consequences.
