Pad*menes - It seems the post that you are concerned about is primarily answering the questions the thread author asked in their first post. It is not flaming any players, and while it is taking a jab at a couple of the gods in an aside remark, none of the responses following that post have taken the 'bait' and the discussion is still on topic.
At this point, no moderator action is needed, and would only serve to bring attention to the remarks, which have so far been ignored, (which is the best way to handle flamebait.)
