Allowing an accusation that Pope Benedict was Nazi because he was in the Hitler youth, while banning a rebuttal that explained what that meant makes the Hitler Youth argument against Francis and all Catholics a Reductio ad Hitlerum fallacy.
Allowing folks to point out the wickedness of some Catholic priests, while banning posts that are show that they shouldn't be casting the first stone by posting examples of equally wicked protestant ministers, or a rebuttal about the infiltration of the Catholic Church... is siding with the Protestants.
Damning Catholics for making a idol of the Cross (seriously?) and then deleting that along with an explanation that Catholics keep the crucifix to remind themselves of the how great the sacrifice of Christ was, is anti-Catholic bias. If the Crucifix is part of the problem that some see with Catholicism, why not let the use of the Crucifix be explained.
