It's a good ruling if it helps increase state sovereignty.
I just hope that this isn't yet another example of racists trying to usurp state sovereignty arguments to suit their purposes. I'd love it if now that this law is gone, absolutely no racist bull**** follows. If that happens, I'll be very happy. If racist bull**** ensues, though, it'll be yet another instance of racists undermining the state's rights platform with their ignorant bull****.
