If they are not directly affecting your state and salvation, pray and sacrifice for them. Let go of anything else as it is of no immediate concern.
I wouldn't go that far. First of all, even according to YOU I have reason to concern myself with Frs. Hewko and Pfeiffer. Because they are "at war" with Bp. Zendejas and Bp. Williamson, and doing everything in their power to kill (insofar lies in their power) both the chapel I attend and the larger "priory" chapel in Houston that it depends on. So yeah, that affects the salvation of not just me but my wife and 9 children as well -- and all other Trad Catholics in South-Central Texas.
So yes, this isn't just gossip or talking about something that has no bearing on me or the good of souls.
If we were talking about fallen priests getting married and leaving the priesthood? Yes, I'd agree with you 100%. Pray for them and move on. No good is done by pressing your nose deeply into a cow patty. Just note the cow patty silently, avoid stepping in it, and move on. We had a couple threads like this on CI in the past, and that was the advice given to me by my priest.
But Fr. Hewko didn't leave the priesthood. He is actively preaching, and attacking good priests. So yeah, the word needs to get out that IF YOU HAVE OTHER OPTIONS FOR MASS, USE THEM and beware. Keep AT LEAST both eyes open if you must have dealings with either of these priests.
As for "we've all made prudential errors". Well, I haven't. At least not like they have done! And they haven't repented of their gross errors yet. I'm not saying I'm perfect OR sinless, but to paraphrase St. Paul I am "not mindful of any thing" that I need to publicly recant or repent of, where my prudential mistake
caused ongoing public damage up to the present day, and so I need to repair it. Nope, I have ZERO such sins weighing on me. Being free of such sins doesn't make me a saint, but it's a humble start.
