If you don't follow the rules, how does that make you part of the group? It's like saying anyone can join any group, regardless if you are a practitioner or not, regardless if you follow the rules or not, and everyone in the group is responsible for this one individual.
If a Christian felt that the bible compelled him to go kill his family, and he did it, and Christians say that isn't the way of Christ, apparently he is a Christians, so suddenly all Christians are bad people. Or I have a better one, a human decides to kill 6 million people, because it is the way of the human being, but everyone says that's not the way of the human, but that's fine, all humans are evil.
Great logic.
