Law professor and dean Erwin Chemerinsky has written this op-ed about the tone of Justice Scalia's opinions.
Here's the beginning:
Justice Antonin Scalia is setting a terrible example for young lawyers. Ignore, for now, his jurisprudence, his famously strict originalism; it's his tone that's the problem.
I have taught argumentation for many years, first as an instructor to high school and college debaters, currently as a law professor. Throughout my career I have always cautioned students away from nastiness as a crutch for those who cannot win using reason or legal precedent. I have told them to stick to persuasion and to dissecting the opposition's logical fallacies.
