Be that as it may, the serious question here is whether this is within the Magistrates' jurisdiction. If it's not, we need to figure out whose jurisdiction it is.
I think Tom has already definitively answered this question. It is not.
Regarding who
is responsible for this, I would argue that no one is. This kind of religion is not against any rule. Is it officially discouraged and detested? Yes. But it's not actually a violation of anything on a non-SMA island. If specific players in the community or the community at large find such religions to be distasteful, then they should take steps to discourage them by creating IC disincentives to their creation and maintenance. There are many perfectly justifiable IC reasons for religious characters to detest a 'religion' such as the Path of Chivalry and seek to oppose or destroy it.
