Robert Bork wrote and said things that were viewed as controversial by some people but it was completely defensible and intellectually consistent with conservatism. He deserved better. This kid, when you get down to brass tacks, basically said blacks are lazy, Asians and Indians are dishonest, and btw I have a Nazi streak. And you think people should go to the mat to defend that garbage?
You could do what the Democrats do. Change the subject and move on.
Or you could do what I'm doing. Not care in the slightest.
