The answer would have people going on a wild goose chase. It makes Catholisism out to have turned completely mystic, upholding other religions as true and one of the late Pope's to be the Antichrist.
I realize it was an attempt to answer the question by pointing out a supposed premise flaw in your question (hence no mod deletion for being out of scope) it does so in a totally bogus way that is not actually representative of Catholic doctrine. In other words it's a wrong answer (hence my downvote).
So why no comment? First of all, it seems patently obvious to me that the answer was wrong. Further more a few clicks through to the author who wrote it and their other posts and profile lead me to believe that I wasn't going to convince them they'd made a mistake by leaving a comment explaining my downvote. It also looked like they were highly likely to argue with me, so I decided not to waste my time.
Frankly it looks like the system is working pretty well. I'd imagine most of the other voters went through a similar thought process. The answer is wrong (and dangerously so) and the community has clearly marked it as such. Comments should be used when a post can be improved and the OP can learn something, not for debating people with bogus theologies. At most it could use a comment would say "This is not representative of Catholisism", but I think the downvotes pretty much speak to that effect already and who wants to leave the comment that's going to make you the target?
There, bulls-eye is on me.
