Two straw man arguments immediately discredit them on their introductory page.
the first major figure to hold that those who die with the baptism of desire or blood will nevertheless go to hell was the Jesuit Fr. Leonard Feeney
Father Feeney never said that those who die in a state of justification through BoD go to hell.
Another error promoted by the Rev. Crawford (one that is likewise shared by some other sedevacantists and non-sedevacantists) is the idea that periodic continence (aka the rhythm method) among married couples is intrinsically evil and therefore never permitted.
Nobody says it's "intrinsically evil" ... but it's evil due to formal motive. Also a false link between having to be intrinsically evil in order to be "never permitted". Murder, for instance, is never permitted, even though taking a human life is not intrinsically evil. It's based on the formal motive.
So, in a word, this is just more garbage from the usual suspects (the sedevacantists) a couple of ignoramuses who think they're theologians (lots of sedevantists think that their armchair theology suffices to depose popes).
