Separating a movement from it's supporters is practically impossible. It, whatever the movement is, is only a movement because of its supporters, and they will invariably be judged by those viewing the movement. No matter how much we try to avoid it, human nature is inescapable.

Almost every advocate of gun restrictions is a fan of nanny state government
