My friend Rhology engaged in a three part dialog with an imam, which is recorded. Interestingly, the imam suggested that Islam does not permit "debate," as such (mentioned near the beginning of the first part). I thought Rhology did a good job of highlighting some of the important issues. It was relatively low key and calm.
