This person is persistently trolling the Catholic threads. Based on what I have read, I see no indication of an open mind or sincere attempt to engage, but rather a desire to wage war on what he/she perceives as an abomination from the perspective of his/her particular Protestant sect. If there is no sincerity of engagement other than a mission to take down the Church, can we better focus our dialog on more sincere and fruitful correspondents?
Let us not forget that non Trinitarians who spurn the Nicene Creed can hardly be called Christians. I’m not sure I’d paint them with the term Protestant either, unless we use the term to encompass everything that has developed from the Reformation, and often from the Restoration.
