So do you or do you not deny that the Roman church was a corrupt political oligarchy at the time of The Reformation?

Formulated the way you have, presuming you are referring to the Catholic Church, there’s no need to deny it. It’s false.

I deny the question has any more bearing on the rectitude of the reformers actions than David's anointing had on reign of Saul.

For an brief, intelligent account of the Refomraiton from an RC POV, I cannot recommend enough:

Adam, Karl; Roots of the Reformation, Coming HOme Resources, Zanesville, Ohio, 2000 - but from lectures given in 1947.

Short answer: There was a LOT of corruption going on.
