At which mosques are the imams preaching murder, Vik? If you have information on this you should communicate to law enforcement about it, so they can protect you. That’s their job.

Calling the police is insufficient, since as I pointed out in the comment you quote, such preaching by imams is currently viewed as protected free speech.

So, if the argument is, anything calling itself a religion must be protected, then I would like to hear what is proposed in answer to the question, “How are we to protect ourselves from Imams who call on Muslims to commit murder in the name of Islam?”
