From a reader:
Whenever I hear that something wrongly decided has been a precedent for so long that it must be kept, I ask the person saying that if he agrees that Plessy v. Ferguson should never have been overturned, given that it was precedent for 58 years. Likewise, I also ask if the person would agree that Brown v. Board of Education should have gone the other way, given the great disruption it caused. Oddly, no one I’ve ever asked has agreed.
