Leave Wealthy, Powerful, Life-tenured Republicans Aloooonnnnnne!
The proliferating conservative meme that criticizing legal arguments you disagree with is some kind of unethical intimidation is probably too stupid to require an elaborate rebuttal, although Mark Tushnet does the job very effectively.
Although, in fairness, can anyone remember a conservative criticizing a Supreme Court decision they disagree with? I find it hard to imagine Republicans engaging in such incivility. I think even the most detailed search would fail to find the slightest criticism of Roe v. Wade or Kelo v. New London.
