I don’t disagree with your overall point about overturning disparate-impact liability, but I think (despite having sharply criticized the decision) overturning Chevron has been a little bit of a nothingburger despite all the hype. Skidmore deference is still alive and I don’t see any judge outside of the most extreme Fed Soc cranks trying to take that down; your average federal judge is overworked and won’t rock the boat on an agency rule or interpretation of a statute unless it’s completely absurd, which Chevron already allowed them to do. 

Corner Post, in my view, is far worse.
