“RC” is just an abbreviation, just like “OPC” is.
If it’s acceptable to use abbreviations for Protestant Churches, it’s acceptable to use them for Catholic churches.
Don’t be hypocritical and grow a thicker skin.
I’ve heard of some ET’s growing meat in vats for eating.
Maybe we could see if they’d take on a project of growing some thicker skins in vats for the Roman Catholic rabid clique folks hereon.
That isn't the abbreviation you formerly used which was clearly offensive and gutter language not befitting the Religion Forum.
They are both acronyms, not abbreviations. The difference is that OPC is a acronym actually used by the Orthodox Presbyterian Church and lacks the history of prejudice, suppression and terrorism that the RC does.
