I agree it looks like Caminiti is trying to impose a form of Sharia-like Christianity which is not good. However he needs therapy not jail.
He has the right to preach Sharia law if he desires. Now, with that said, where is the line? Would he be allowed to preach that people should commit murder? What if a private citizen told his neighbor that the neighbor should spank his child? Can he be sent to prison? Very slippery slope here.
