The Trads who gave him a bad taste in his mouth will have to answer to God for the part they played in Skojec's discouragement and apostasy.
If I recall correctly, was it not some FSSP priest who did not allow one of his children to receive First Communion because they stayed away from the classes and whatnot due to "COVID"? Certainly the priest, in charity, should have just offered to quiz the child independently to determine if he/she was ready. Of course, if you make the classes mandatory, but then make exceptions, are they mandatory? That's probably what the priest was thinking, but he probably could have made an exception in this case due to the nonsensical COVID situation ... or just given him/her private instruction to make up for the missed classes.
In any case, throwing the faith overboard for something that petty ... I find rather astounding. Sure, I've heard of people leaving the faith due to things like being assaulted by a pedophile priest or whatnot, but some some administrative nonsense? In fact, if I felt that my child was ready, properly catechized, had the right dispositions, etc. ... I'd just have him approach the Sacraments anyway. There's no canonical requirement of any kind with regard to a specific preparation class for Holy Communion. Or he could have sought out another priest, whether Eastern Rite or some other Traditional priest (no issues there, since most of them receive Holy Communion even before the age of reason, even at their Baptism). But just because a priest made a bad/bureaucratic judgment call?
He got very bitter after that, and it was only then when he started lashing out against "Trads", but I've seen the same kind of behavior for NO priests, and it was most likely that this FSSP priest was following some kind of diocesan policy anyway. Most truly Traditional priests I've known would and have in fact provided individual instruction as needed. In fact, my brother in law (husband of my wife's sister) wanted to convert and went to the Novus Ordo, who told him it would be a year or so of nonsensical classes (that would probably just undermine his faith) ... when the man had spent years getting to know the faith through his wife and was determined to become a Catholic. So I advised that he go to an Eastern Rite priest (they were not on board with Traditional Catholicism), and this priest met with him several times, got his history, determined whether or not had had the proper dispositions, etc. and within a few weeks he received conditional Baptism and the Sacraments. As a side note, he was the son of a Protestant preacher and did not convert at their marriage, but after a few years, his wife (my wife's sister) put a Green Scapular under his mattress, and within a few weeks of that he announced out of the blue that he had decided he wanted to become a Catholic.
