Contributing isn't the same as agreeing. Stating that the OP's work is essentially meaningless, because the basic premise upon which it is founded is fundamentally flawed, is still contributing to the discussion, whether you agree with that statement or not. Your posts, however, have contributed nothing to the actual topic of hand, and only been directed at others who have been posting on the subject. If you want to slam anyone for not contributing, I suggest you look a little closer to home.
