You are not slow. I am vague due to time constraints.I've got a sec now; I'll elaborate.
I think your letter was spot on. To be described as more Catholic than others in a pejorative way is typical and familiar. But it's true, only because you have made the decision, by exerting your will, to learn the mind of the Church through her immense paper trail. You have truth and knowlege on your side and that makes you more Catholic than others because they have lies and myths on their side.
Gotta run.
Of course, even the idea that one can be more Catholic than another, and have a resentment or malice because of it, stinks of some kind of egalitarian sentiment. It's not that you are more Catholic. It's actually the fact that your correspondent isn't Catholic enough. Certainly V2 didn't change one iota of "Catholic theology", and it would be perfectly proper to hammer facts home, at every opportunity. Sure, one is going to be called judgemental, rigid, hyper-religious, but damn the torpedoes, full speed ahead. A spontaneous negative reaction that vilifies the speaker of truth is often replaced by understanding, and it is understanding that your opponents desperately need.
