There is a major anti-Islamic who goes by the name of Ali Sina, this certain apologist also claims to have been a former Muslim, which is hard to believe due to his lack of knowledge concerning the Islamic faith.
Ali Sina claims to be Islam's worst nightmare and that he is so smart and unbeatable, he is very over-zealous you could say. In fact many of Ali Sina's supporters also go around claiming how good he is and how no Muslim can debate him.
Well since I keep hearing all this I thought I would issue an open debate challenge to Ali Sina, in fact we will debate a topic he likes which is:
Muhammad: Is he a Prophet?
Ali Sina often debates this topic, trying to dis-credit the prophet as much as he can, so therefore this will be a perfect debate for Ali Sina, and since he is so good as he and his followers claim him to be, then I see no reason as to why he cant accept a nice debate challenge.
