There is certainly plenty to analyse in the phrase "failed seminarian" as used by Tridentinus. Whether he likes it or not, it is quite revealing. Also revealing is the way he claimed I'd not understand because I'm probably not even a Catholic. When I revealed that I am not only a Catholic but also a priest, then he claimed I wouldn't understand because I never left. 
I am reminded of the saying - The trouble with extreme self righteousness is that, no matter what you say or do to such a person, you merely prove them right.
In any case, he's not here to discuss or even convince. He's here to disrupt.
