See, now that's clearly the mark of someone who has abandoned any pretense at objective scholarship. Agree with him or disagree with him if you like, but only dilettantes and fools can deny the intellect of Antonin Scalia. And I don't agree with Scalia on everything, but I can make a very good case that in terms of pure intellectual firepower, there is Scalia and Oliver Wendell Holmes in one camp, and everyone else in the other. And honest liberals who are serious students of the court cannot help but also admit that he is brilliant - as opposed to your professor, who is either a fool, a fraud, or not a serious scholar. Either way, that sort of attitude is the attitude of someone who does not belong in academia.
In seven years of teaching college, that attitude is all I saw.
