FYI Catholic Family News is a Feeneyite publication. The SSPX, the SSPV and the sedevacantists all reject the belief of excommunicated priest Leonard Feeney that there is no salvation outside the Catholic Church. Even pre-Vatican II popes believed in baptism of desire and Feeney was excommunicated by none other than Pius XII. Feeney was the Catholic version of Bob Jones and Jack Chick.
This is the logical fallacy of "Poisoning the Well." If you have evidence that Catholic Family News is a "Feeneyite" publication, present it. If you think this article is tainted with "Feeneyism," then argue your point. Your comparison of Fr. Feeney to Bob Jones and Jack Chick is unwarranted calumny, as Fr. Feeney was orthodox except regarding the Baptism of Blood and Desire.
"No salvation outside the Catholic Church" is a dogma of our Faith - not a Feeneyite invention.
Having said that, you're quite right to point out problems with some of the Feeneyite interpretations.
Here is an article which addresses this issue in greater depth: http://www.sspx.org/miscellaneous/fr_feeney_catholic_doctrine.htm
Please note that even protestant baptisms may be valid:
Already in the 3rd century, the Church defined that the fact that it is a heretic who administers the sacrament of baptism does not make it invalid (Denziger, 110). The baptisms of Protestants are consequently to be considered valid, unless a reasonable and prudent doubt occurs as to a defect of the required matter, form or intention (Cf. Roman Ritual, Titulus II, Caput 3, §11 & 12).
