Ahh but Anti Catholicism is simply a another set of facts that we don’t agree with...Right. Very interesting.
But what constitutes "hate mongering" is up to moderators. We know it when we see it.
As to the rest, when one belief spawns from another it is not unusual for both to condemn the other in the harshest terms possible, e.g. anathema, heresy, apostate, cult, Satanic. Such terms and beliefs often become part of the official documents of the religion. The contempt cuts both ways and is aired only in "open" RF debate.
