So what? There are High-Church Anglicans who vehemently oppose this stuff. I see this kind of thing quite a bit with modern Catholic apologists.( taking joy in and mocking the bad behavior of other Christians) I hate to say this, but the Church( in its current state) is in no place to criticize or mock anyone. Let's straighten the Church out first. When we have our heads on straight, we can help others get their heads on straight as well.

Fr. Reginald Garrigou-Lagrange

We know nothing more reprehensible than the nambypambyism babbled by sentimental Catholics about the good faith of "our separated brethren." There may be persons in good faith amongst Protestants, but, if so, they do not lack opportunities of showing it, and of coming out from the Babylon in which they have been reared. Men cannot be saved without Christ, for there is no other name given under heaven whereby they can be saved. Without faith it is impossible to please God, and he that cometh to God must believe that he is, and is the remunerator of them that seek him ; and how can those be saved by Christ who adhere to the party that rejects him and makes war on him ; and how can they have faith or believe in God who commune with those who resolve all faith, all belief, all truth indeed, into a mere opinion, or an inward sentiment, varying with each individual?

If Catholicity is Christian, if reason is authoritative in its own province, nothing is more certain than that Protestantism is in no sense Christian, and that persons living and dying Protestants cannot be saved. It is a stultification of common sense to maintain the contrary, and besides, it practically neutralizes all our efforts to convert Protestants, and to bring them to a living and saving faith in Christ. We know what theologians say of invincible ignorance, and we do not contradict them. Invincible ignorance excuses from sin in that whereof one is invincibly ignorant; but it gives no faith, no virtue ; and without faith, without positive virtue, no man can be saved. The man who holds implicitly the Catholic faith, but errs through invincible ignorance with regard to some of its consectaria, and even dogmas, may be saved ; but how can a man be said to hold implicitly the Catholic faith, who holds nothing, or rejects every principle, that implies it? It is not safe to apply to Protestants, who really deny everything catholic, a rule that is very just when applied to sincere but ignorant Catholics, or Catholics that err through inculpable ignorance. Protestantism does not stand on the footing of ordinary heterodoxy ; it is no more Christian than was Greek and Roman paganism.

Finally some of these misguided people attempt to persuade themselves and others that men are not saved only in the Catholic religion, but that even heretics may attain eternal life.
