:::::"The issue is a subject of some controversy, as you probably know."  I agree.  And those who have made a contribution to the conversation should be cited.  However, there is a difference between making a contribution to the conversation, and responding to a question.  Because it is "a subject of some controversy" does that mean every person's WP page should have their position listed?  Is every person's every word on a controversial subject worth noting on WP?  Mentioning it on WP gives someone the impression that this is a major topic of his.  This is misleading.  WP isn't a comprehensive biography, it is an introduction.  Therefore, inclusion should be based on whether or not it is an important theme in his work.  Christians, as a whole, have a lot of views about a lot of things, many of them controversial.  There's a big book (called the Bible) that contains all sorts of scandalous material, which Christians normally assent to.  Is listing each one on each Christian's page worthwhile?  That would be ridiculous.  Nor should Muslims be cited for every thing listed in the Quran, even if they have answered a question on it in public.  It should only contain the ones which they have made actual contributions to the conversations for.
