Sure. I don't bother to be precise because I've already put several hours into this silly discussion. Again, which sede group are you a part of? Dolan/Sanborn and the CMRI hold to BOD(Dolan has said it's a mortal sin to deny it)
The gentleman to whom you are talking to has put 25 years into this discussion and is very patiently attempting to teach you to be precise, lest you become a heretic like the Pelagians. Precision is everything when you are attempting to skirt all those dogmas. You need to grow up.
The gentleman is not a sedevacantes and neither am I. But we are not Novus Ordo or resistance either. You will learn a lot if you learn to abandon the demonizing you have been programmed to use by (maybe) the SSPX against the sedes and the strict EENSers (which you call heretics, schismatics). My confessor, may he rest in peace, was ordained in the early 1950's, our chapel, had mostly SSPX people, but we also had many sedes and strict EENSers, and we all got along. After his death, he was replaced by SSPX, and they chased away the sedes and created conflict. To make a long story short, I concluded that these groups, SSPX, Dolan, CMRI etc. are just protecting their business in all of this demonizing. I do not follow such people. I may attend their mass if I am certain they are valid priests, but I do not SWALLOW all of their teachings.
