I read your post and AM's responses. He is simply asking you to flesh your OP out. This is standard operating procedure. If you are unwilling to work on your OP why should anyone think you will be willing to put a good effort into the discussion itself.
The requests are not terribly onerous. If this is such an important point why are you not willing to flesh the OP out with material that will be needed early on in the discussion anyway? It will just save a bit of time and stop using up some of the 300 posts getting to the point.
