Very well. It is not uncommon to hear that a Catholic poster has been brainwashed by the Church. I will know that it is a violation of the etiquette going forward.
You might want to throw out the Luther "invented his theology to support his masturbation habit" too. Many people believe Luther's theological concepts based upon a Scriptural understanding. You may disagree with that standing. But, what was said about it was a bit across the lines of, uh, etiquette.
