Moderator's note to follow up several of the above posts about this topic:
People, this is not a debating club, with strict rules about what constitutes a valid point and which style is allowed. The Downs has a long-standing tradition of mixing serious discussion with humour, and any member has the right to state her/his opinion. Of course it will find a better reception with others if it is founded on facts and supported by quotes, but the balrog question has not been conclusively decided elsewhere, and I doubt that we shall find the one correct answer here.
Tell us your thoughts, tell us why - and if you can convince us, great! If not, you still have the right to express your opinion, as long as you do so politely and in a friendly manner.
Now let's not debate about the debate - anyone who doesn't like this one is welcome to find another thread that suits her/him better! Better yet, find a topic we haven't discussed yet and start a new thread!
