The really hilarious thing about anti-Thucists is that they have double-standards that they do not apply to their own people.
If it's about doubting the moral character of someone, I would worry far more about this :

I do not see the larpers pretending to be Catholic doubting all the ordinations done by John Paul II. Their double-standards show that they are nothing like God, they are simply a bunch of hypocrites who are envious of traditional christians.
If some of the larpers were willing to use logic, and to apply the consequences of their reasoning to other matters, perhaps I could take them seriously. But they do not, proving they are but Pharisees larping as Christians.
If Thuc's ordinations are invalid, not a single ordination in the Vatican II polytheist sect can be considered valid, according to the same criteria. In that case, it simply means Catholicism is a false religion.
Not only they are in communion with polytheists, but they are in fact apostates.
