" Because so many people in today's world have questions about the Muslim faith, and because it has been stated that your parents and grandparents are Muslims, that you bear a Muslim name, in fact, but that you profess to be a Christain, would you be willing to assure those you might represent that you do not view the Christains and Jewish peoples ( along with other non-muslim faiths) of America as infidels? Would you be willing to say so in a direct statement?"
This is poorly worded, by you catch my drift, I'm sure. I know I would like to ask him a question about his heritage, why not? If we are the sum of our experiences, then this matters in today's world of creeping terrorism.
Because if our side is not booed off the stage immediately for bigotry (not all Muslims are a threat), the question is easily answered, because there is only one correct answer. Once we get the only answer we could have possibly received, we cannot even verify the truth in it. In the end, we make him the victim because we are questioning his character on account of his heritage. There are hundreds of opportunities from his own record to question his character. This one is something that is best left to someone else.
Besides, he is already on the record as saying that he believes no one goes to Hell. That does not square with a Muslim's beliefs. Unitarianism, while its "practitioners" consider themselves Christians, is mostly considered a cult by contemporary mainstream theologians (Catholics, Baptists, Methodists, etc.).
