well, Paul made the statement, 29 I know that after my departure savage wolves will come in among you, not sparing the flock, so i hope you see that it is not for me to point fingers and personally identify who these are, because i am not qualified. But i can suggest that the passage deserves a hearing, and i can note that both Catholics and Est'd Christians seem to have no problem commending themselves to each other now. So imo i think it is naive to suggest that i have been completely and utterly proven wrong there; but i think it is equally wrong to suggest that "Catholic = antichrist" or similar nonsense, too.
As to part 2 there, i guess it depends upon if one has come to understand that someone of a different belief system than them might be accepted by God just like they are, or not, and in my experience Catholics, the people, seem divided on this, while i am not sure where the official position is these days? My test for that is usually if one thinks a practicing Muslim still needs "salvation" or not.
Anarchy is ultimately just an alternative--now--economic system, that kind of inevitably results in a certain political--or rather anti-political--position, being as how our politics is so intrinsic to our "economy" now. I guess it does also result in a religious--or anti-religious--position, also, but i should point out that real Anarchists have no desire to, say, overthrow the current government, or for that matter the current religious establishment.
We, most of us, anyway, harbor no illusions that we could do a better job, and i would like to make clear that if i had some magic button i could push that would eliminate the RCC or religion in general, i would not push it. Anabaptists might be the best image of Anarchists that i could supply, right now, even if most of them are kind of statist, making various accommodations so that they can exist under Fascism; voting, paying any kind of tax, etc., which a hardcore Anarchist does not do.
