Which is another vain substitute for an argument, while it remains that your attempts i have dealt with which seek to provide one for Rome are fallacious and an argument against Rome. Thus it is indeed in her best interest to not engage in more.
At least your provide evidence of some tactical wisdom in medieval Rome which at one time banned the laity from engaging in debate about faith with souls such as here.
Quinisext Ecumenical Council, Canon 64: It does not befit a layman to dispute or teach publicly, thus claiming for himself authority to teach, but he should yield to the order appointed by the Lord, and to open his ears to those who have received the grace to teach, and be taught by them divine things; for in one Church God has made "different members," according to the word of the Apostle... But if any one be found weakening [disobeying] the present canon, he is to be cut off for forty days. — http://www.newadvent.org/fathers/3814.htm
We furthermore forbid any lay person to engage in dispute, either private or public, concerning the Catholic Faith. Whosoever shall act contrary to this decree, let him be bound in the fetters of excommunication. — Pope Alexander IV (1254-1261) in “Sextus Decretalium”, Lib. V, c. ii: http://oce.catholic.com/index.php?title=Religious_Discussions
Can. 831 §1 Unless there is a just and reasonable cause, no member of Christ's faithful may write in newspapers, pamphlets or periodicals which clearly are accustomed to attack the catholic religion or good morals. Clerics and members of religious institutes may write in them only with the permission of the local Ordinary. - http://www.intratext.com/IXT/ENG0017/_P2P.HTM
...the clergy are not free to engage in public disputes on religion without due authorization. In the Collectanea S. Cong. de Prop. Fide" (p. 102, n. 294) we find the following decree, issued 8 March, 1625: "The Sacred Congregation has ordered that public discussions shall not be held with heretics, because for the most part, either owing to their loquacity or audacity or to the applause of the audience, error prevails and the truth is crushed. But should it happen that such a discussion is unavoidable, notice must first be given to the S. Congregation, which, after weighing the circumstances of time and persons, will prescribe in detail what is to be done. The Sacred Congregation enforced this decree with such vigour, that the custom of holding public disputes with heretics wellnigh fell into desuetude.
“Do not converse with heretics even for the sake of defending the faith, for fear lest their words instil their poison in your mind.” Bl. Isaias Boner of Krakow (Polish, Augustinian priest, theologian, professor of Scripture, d. 1471)
“...the Church forbids the faithful to communicate with those unbelievers who have forsaken the faith they once received, either by corrupting the faith, as heretics, or by entirely renouncing the faith, as apostates, because the Church pronounces sentence of excommunication on both.” St. Thomas Aquinas, Summa Theologica, Article 9, “Whether it is lawful to communicate with unbelievers?”; http://www.newadvent.org/summa/3010.htm
“On the other hand, there are unbelievers who at some time have accepted the faith, and professed it, such as heretics and all apostates: such should be submitted even to bodily compulsion, that they may fulfil what they have promised, and hold what they, at one time, received.” St. Thomas Aquinas, Summa Theologica, Article 8. “Whether unbelievers ought to be compelled to the faith?”
Pope Innocent III, Cum ex Officii Nostri of 1207: In order altogether to remove the patrimony of St. Peter from heretics, we decree as a perpetual law, that whatsoever heretic, especially if he be a Patarene, shall be found therein, shall immediately be taken and delivered to the secular court to be punished according to the law. All his goods also shall be sold, so that he who took him shall receive one part; another shall go the court which convicted him, and the third shall be applied to the building of prisons in the country wherein he was taken. The house, however, in which a heretic has been received shall be altogether destroyed, nor shall anyone presume to rebuild it; but let that which was a den of iniquity become a receptacle of filth. Moreover, their believers and defenders shall be fined one fourth part of their goods, which shall be applied to the service of the public. — Cum ex Officii Nostri Pope Innocent III, 1207, Inquisition, by Edward Peters, p. 49 review
if a temporal ruler, after having been requested and admonished by the Church, should neglect to cleanse his territory of this heretical foulness, let him be excommunicated by the metropolitan and the other bishops of the province. If he refuses to make satisfaction within a year, let the matter be made known to the supreme pontiff, that he may declare the ruler’s vassals absolved from their allegiance and may offer the territory to be ruled lay Catholics, who on the extermination of the heretics may possess it without hindrance and preserve it in the purity of faith; the right, however, of the chief ruler is to be respected as long as he offers no obstacle in this matter and permits freedom of action.
The same law is to be observed in regard to those who have no chief rulers (that is, are independent). Catholics who have girded themselves with the cross for the extermination of the heretics, shall enjoy the indulgences and privileges granted to those who go in defense of the Holy Land.
