Please Trid, the head vicar of my parish acknowledges the existence of man-made rules within the RCC... would you accuse him of being a "Catholic dissenter" as well? 

It is not convenient to cite the paradigm shift of the Constantine era, it is historical fact. Providing one can own up to this (such as most of us do), there is no real shame in this, if for no other reason than not repeating past mistakes. In summary, theological overreach should not be held up as a paragon of virtue, especially when there is clear and convincing evidence to the contrary.
