Have been added to Da Rulz:
23. The following terms are pejorative and their use as actual descriptors (as opposed, for example, to quoting someone else's use of them for purposes of critique) constitutes rudeness: "Romanist," "Romish," "Roman" (when used to mean or as a substitute for "Catholic"), "Roman Church" (when used to mean the entire Catholic Church, as opposed to the Roman church sui iuris that exists within the Catholic Church), "Papist," Papistic," "Papistical," "Popish," and any cognate terms based on the terms "Roman" or "Pope."
The term to be used on this blog is Catholic, without scare quotes.
This is a Catholic blog, and Catholics are to be called Catholics on it.
24. It constitutes rudeness to make inflammatory assertions that one is not prepared to back up by anything more than hearsay (e.g., "Mother Theresa prayed to Hindu idols. I know because my friend said so.").
Inflammatory claims are those likely to inflame passions. An inflammatory claim can be true. But because of its emotion-stirring character, it requires concrete evidence (more than just hearsay) to back it up if the discourse is to be kept civil and not degenerate into an impassioned muddle.
(NOTE: I've added clarifiers to these rules based on issues that came up in the combox below. The corresponding changes have been made to Da Rulz page as well.)
