There is no reason for the SSPX to write all those books about BOD if it was to answer the "Feenyites".
Here's all that needed to be said:
"You strict interpreters of the Council of Trent Canons on the Sacrament of Baptism, Canons 2 and 5, are only putting up this long debate over a catechumen who dies by accident before being baptized? This is a waste of ink!"
----------------------------------------------------------
The SSPX writes all of those books for a reason. I think that two of the reasons are:
1) they don't want to be further "stigmatized' by Rome as "Feeneyites", so they use the Feeneyites as whipping boys to show Rome that the SSPX is liberal, just like the conciliar church with regard to EENS.
2) All the priests of the SSPX have been taught in their seminaries that non-Catholics can be saved, even if they are not baptized nor have a desire to be baptized (implicit faith, the complete opposite of baptism of desire). Here are the Abp. himself and Bishop Fellay, saying it:
From the book Against the Heresies, by Archbishop Marcel Lefebvre:
1. Page 216: “Evidently, certain distinctions must be made. Souls can be saved in a religion other than the Catholic religion (Protestantism, Islam, Buddhism, etc.), but not by this religion. There may be souls who, not knowing Our Lord, have by the grace of the good Lord, good interior dispositions, who submit to God...But some of these persons make an act of love which implicitly is equivalent to baptism of desire. It is uniquely by this means that they are able to be saved.”
2.Page 217: “One cannot say, then, that no one is saved in these religions…”
Pages 217-218: “This is then what Pius IX said and what he condemned. It is necessary to understand the formulation that was so often employed by the Fathers of the Church: ‘Outside the Church there is no salvation.’ When we say that, it is incorrectly believed that we think that all the Protestants, all the Moslems, all the Buddhists, all those who do not publicly belong to the Catholic Church go to hell. Now, I repeat, it is possible for someone to be saved in these religions, but they are saved by the Church, and so the formulation is true: Extra Ecclesiam Nulla Salus. This must be preached.”

Bishop Bernard Fellay, Conference in Denver, Co., Feb. 18, 2006: “We know that there are two other baptisms, that of desire and that of blood. These produce an invisible but real link with Christ but do not produce all of the effects which are received in the baptism of water… And the Church has always taught that you have people who will be in heaven, who are in the state of grace, who have been saved without knowing the Catholic Church. We know this. And yet, how is it possible if you cannot be saved outside the Church? It is absolutely true that they will be saved through the Catholic Church because they will be united to Christ, to the Mystical Body of Christ, which is the Catholic Church. It will, however, remain invisible, because this visible link is impossible for them. Consider a Hindu in Tibet who has no knowledge of the Catholic Church. He lives according to his conscience and to the laws which God has put into his heart. He can be in the state of grace, and if he dies in this state of grace, he will go to heaven.” (The Angelus, “A Talk Heard Round the World,” April, 2006, p. 5.)

So much for desire to be baptized, or desire to be a Catholic, or a catechumen, or a martyr
This is the Achilles heal of all the traditional priests ordained by the SSPX. If they can be led to accept even in implicit faith, then the accepting of the teaching that Vatican II contains no errors when interpreted according to tradition, is an easy step.
