If the crux of the matter is "Were the Thuc consecrations all valid vis a vis his mind?", for Tom to say "I don't think they were since he acted quite erratically and strangely and I take that as a sign of a deranged mind" and try to bring up arguments, be they good or bad, is not slander or a sin, it's just one of the opinions on the question, just like when people argued whether Francis was a formal heretic, it's not slander, even though being a heretic is obviously bad.
Using this same logic, don't you think that the exact same argument could be made regarding the last few years of Bp. Williamson's life? In a way, even more so, since the internet made it far easier to make public certain statements about Medjugorje and Garabandal? Could HE +Williamson also be accused of senility with regards to his clerical actions in the last few years he was alive? Was he not performing Consecrations that were only made public after the fact and during a timeframe that he could have been accused of not having all of his wits about him?
Please understand that I have much respect for His Excellency, Bp Williamson. I only point this out to highlight that many of the same things used to slander Abp Thuc could easily be applied to Bp Williamson as well. And even though I'm just a crazy Sedevacantist, I would defend Bp Williamson in the light of him being a man likely recognizing that he was in the sunset of his earthly life, and intending to do as much as possible to preserve the priesthood, perhaps setting aside the prudence he may have once exercised here and there. And should there someday be some Kosik style characters claiming, years after his death, that they were consecrated by Bp Williamson, I would not take that at face value, but in respect to +Williamson, reserve any judgement until sufficient evidence had been produced.
Just wanted to mention that since, even though many that knew him have stated that Abp Thuc was not senile, but very sharp during the timeframe of his consecrations of +Des Lauriers/ +Carmona/ +Zamora, his mental state is still questioned. And I find that accusation particularly interesting from those who would never tolerate such a charge being brought against Bp Williamson.
Side note, I also find it pretty funny that Bp Kelly and the SSPV also sought out an elderly, retired bishop to maintain their line despite their objections to Abp Thuc, lol! The irony is pretty thick there. And btw, yes, I do consider the SSPV line valid. I just find that to be quite interesting.
