I would have no problem at all. Learning about other people's religions is an essential function of a rounded education. When you take God entirely out of the education of children you teach that God is irrelevant. Religion plays an extremely important role in politics and history and to remove any discussion of the beliefs and practices of the major religions is to deny the role that Religion has had in the history of this planet.
So no, I would have no problem about having presentations by various religious groups about their history teachings and practices in the public school arena.
BTW are you suggesting that Mormonism is not Christian?
I am not versed enough, nor really care about “other” people’s religion as long as it does not infringe upon my rights and freedoms. I will leave that to the sycophants and religious zealots that live in a world of hysterical hypocrisy. I just wanted to see if you are consistent. I think religion is fine in school, when it is a private school. Too many variables, and too many students today can’t even get the basic tenants of reading, writing, and arithmetic to worry about religion and other “social” items in public schools. Hire a public school student and watch them struggle to fill out an application.
