Honestly Q, I thought your original post made more sense. Disparaging the wrong religion has a good chance of causing an uproar. Teaching Christianity in a Muslim dominated area is as likely to garner attention as dogging religion. Imagine a Muslim teacher in the bible belt pushing Allah and Muhammad. Or a Jewish teacher in the same area saying Jesus does not exist.
