[Deo volente]

Sorry, but it works both ways. Fundamentalist Protestants and many “Bible-believing Christians” often claim loudly and publicly that Catholics are doomed to burn in hell for all eternity, that they're workers of iniquity, and that their church is the seat of the Antichrist.
It's readily apparent that several of the posters here would heartily agree with those sentiments.
So we're “fighting back”, but always with charity in mind, we hope. I know I fall short of that goal sometimes.

By the way, the official teaching of the Church is NOT that non-Catholics necessarily are lost. You should do a little research, you might be surprised at what you'll find.

Really? Then what does this mean?

"..the Church, a pilgrim now on earth,is necessary for salvation: the one Christ is mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and baptism, and therby affirmed at the same time the necessity of the Church which men enter through baptism as through a door. Hence they could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it, or remain in it." - The Second Vatican Council.
