Hey Bill,
Firstly, all forum discussions are group discussions - so I, or for that matter anyone else, should be free to contribute at will. The PM system exists for more private discussions. Secondly, my opinion is just that - I don't ascribe myself psychic abilities or consider my word on any matter final; if you choose to read me this way then I suggest you're reading me wrong.
Finally, the 787 issues have not involved the NTSB at any point, because the NTSB can only become involved in the event of an accident or serious incident (usually involving injury). Don't make the mistake of assuming that because they are both government agencies they get their marching orders from the same people.
