I, too, think that the OP is onto something, and that this applies not just to clergy who were raised in tradition but anyone raised in Tradition.
I think it depends a lot on how parents raise/teach their children.
This is my personal theory, and I guess the proof will be in the pudding as my children get older ... but in my view children should be taught about the Novus Ordo and exposed to in in carefully managed/supervised doses so as to "inoculate" them and give them a proper understanding/horror of it.
I have seen many Trad families where the parents felt that the best way was to completely shelter their children from everything to the point that I have met several young adults who do not even know what the Novus Ordo is. In my view, it is these ones who are totally and completely ignorant who will not have the holy hatred of that sect necessary, and who may also fall prey to the seductions of, say, the indult or even "conservative" Novus Ordoism. Anecdotally I have seen such results occur. I understand why parents do this -- they rightly want to shield their children from the filth of the modern world -- but I think that sheltering children too much is to leave them very vulnerable when they inevitably have to be exposed to these things at some point unless they go straight to a strictly cloistered monastery after high school.
It is therefore our plan to progressively give our children more information on the Novus Ordo as is appropriate to their age, as they grow. The oldest two are 9 and 8 and they already know the basics and I intend to have them study the Vatican II docuмents by the time they get to high school and prepare essays for me where they point out the errors and contrast them with the teachings of popes and Church counsels. I hope that this will give them "the next best thing" to the hatred of the Novus Ordo that converts such as my wife and myself have. When the children are all high school age we may even go on a field trip to observe a Novus Ordo service then debrief afterwards and discuss all the heresies and problems with it.
