It seems to me that the "special" requirement is the ability to be rational.
I wonder what you mean by "rational." Is that a new code word for "political correct"?
I suspect St. John Chrysostom wouldn't meet your demands for "rationality."
"How dare Christians have the slightest intercourse with Jews, those most miserable of all men. They are lustful, rapacious, greedy, perfidious bandits -- pests of the universe! Indeed, an entire day would not suffice to tell of all their rapine, their avarice, their deception of the poor, their thievery, and their huckstering. Are they not inveterate murderers, destroyers, men possessed by the devil? Jews are impure and impious, and their synagogue is a house of prostitution, a lair of beasts, a place of shame and ridicule, the domicile of the devil, as is also the soul of the Jew. As a matter of fact, Jews worship the devil: their rites are criminal and unchaste; their religion a disease; their synagogue an assembly of crooks, a den of thieves, a cavern of devils, an abyss of perdition! Why are Jews degenerate? Because of their hateful assassination of Christ. This supreme crime lies at the root of their degradation and woes. The rejection and dispersion of the Jews was the work of God, not of emperors. It was done by the wrath of God and because of His absolute abandonment of the Jews. Thus, the Jew will live under the yoke of slavery without end. God hates the Jews, and on Judgment Day He will say to those who sympathize with them., “Depart from Me, for you have had intercourse with My murderers!” Flee, then, from their assemblies, fly from their houses, and, far from venerating the synagogue, hold it in hatred and aversion."
Unfortunately, the "special requirement" here is to walk on eggshells and don't make waves whenever Jewry is the topic of discussion.
Given the state of lunacy of the western world, it's actually a legal requirement. That's why Quis and Vox closed the subforum: so that FE doesn't get in legal trouble. I don't blame them for that, I blame the Jews.
St. John is talking about members of the Jewish religion (post-Temple, of course), not an ethnic group. He would probably have the same to say about Lutherans if he were around then.
The problem is that a lot of people don't make the distinction that St. John does and instead talk about "The Jews", argue about numbers, etc. Really, if people here would look at things as St. John did, the problems with the theology only, there would be no problem. The theology is broken, it causes problems in mindset and worldview, etc. I'll take a risk for that discussion because it's important and relevant.
Discussions about international banking, holocaust numbers, etc., no, I'm not willing to take a risk, and I also disagree with the value or accuracy of those topics.
It all goes back to a broken theology. Free people of that theology and bring them into the Church, any other problems, real or imagined, go away.
So, really, Jayne is right. It has to be rational in the sense that recognizing the only problem with "the Jews" is a false religion that is completely opposed to the Catholic Faith. The Jewish religion relies on, or maybe even exists to, denying that Jesus is the Messiah. You can't get any more opposed to the Catholic Faith than that. And, vice-versa, nothing can be more opposed to Judaism than Catholicism. The point of both religions is the Messiah.
Everything else is just noise and fallout from that simple fact.
