I agree with you; the way the priest went about doing this was wrong. On the other hand, it is extremely insulting that the bishop strongly implies that he is insane, simply because he prefers the Tridentine Mass.
The way this should have been handled is: the bishop should have replied months ago when the priest contacted him, and he should have made some reasonable accomodation of his request, perhaps allowing a weekly Tridentine Mass, which would have been a small step towards a "wide and general application," as per Ecclesia Dei.
No, I'm not an ultra-trad; I've never even been to an Old Mass. I just tire of the antics of too many of our bishops.
