Oneness Apologetics: Dr. David K. Bernard vs. Dr's Jamal Badawi and Shabir Ally
Some people might be tempted to say that Dr. Bernard avoids debates. I don't think he does. I believe he has bigger focus however of his mission in Christianity. This is a twelve video collection of him debating the best of Islamic apologetics in 1998. This starts with video 9.
