Correcting the errors of the Supreme Court is a very difficult proposition. Congress and the President can do it if they had the guts.
Sometimes the individual states can do it, as in this case. That's actually pretty rare.
The average citizen can't do anything about it, ever, except perhaps through the ballot box, but that's a longshot.
Well, here we have to disagree. You and I are doing it right now. We are complaining about the decision and giving our reasons. That is the purpose of the first amendment. Enough complaining and things will get done. (at least that is the idea behind the first)
