Many Catholics -- optimists, perhaps -- are falling for the "better than nothing" fallacy.
They think that if a layman is "rock solid" in his doctrine, then anything goes -- he should be prominent, respected, etc. even if he is committing gross violations of the moral law.
1. Every layman should be rock solid in doctrine. That doesn't mean that each of us should run a public media apostolate.
2. Casting aside one layman whose evils outweigh the good he does, is not a huge loss for the Catholic world.
So if a man is running around naked, saying the Rosary and professing the Apostles Creed, we should leave him alone because he's saying the Rosary and professing good, solid Catholic doctrine? Or, rather, does the indecent exposure override the rather mundane, common virtue of professing the Apostles Creed and saying the Rosary. We have plenty of people in that category; we're not so desperate we need to defend a streaker!
Defenders of apostolates such as TradCatKnight and Fr. Pfeiffer's Boston, KY seminary are using the EXACT SAME ARGUMENT as the classic Trad Catholic teenager who wants to go on dates with non-Catholics, because he's impatient to wait for God to send him good marriage material.
It doesn't matter if there are no eligible bachelors/bachelorettes at your chapel, if you've tried dating Trads already, or you aren't having any luck on CatholicMatch. Dating bad candidates for marriage is a stupid idea, period! If dating a man who doesn't want to work, a woman filled with feminism, etc. is REALLY the best you can do, then perhaps you should open your mind to the idea that God doesn't intend marriage for you!
And if keeping around a man like Pablo is the only way to keep the Seminary going, well...
Yes, it's not a good idea to be picky either. But there are certain "minimums" or standards that you must stick to -- when seeking a marriage partner, or deciding if a given seminary is worthy to exist.
The guy can have physical defects. But what if he doesn't work and doesn't intend to? What if he doesn't value the Catholic Faith? Likewise for a woman: she can have many flaws that you can settle for or put up with. But what if she is proud, un-docile, fully brainwashed by feminism to the point that she would want to be in charge, not have many children (if any), etc.
TL;DR: "Settling" is not a smart idea. In marriage, in seminaries, or YET ANOTHER Trad Catholic media/news source (we have plenty of those).
