You might try ISSD they have a professionals only board.

As for non professionals debates on this you most likely wont find any because alot of mentally ill people don't know alot of the professional side of psychanalitical theorys. They know they are hurting and with what and their treatment plans but unless they are a professional or have access to professional analysis research and material they have none to little knowlege of this stuff in order to enter and discuss/debate analitical theorys.
