Churchill said; “Britain and America are two nations divided by a common language.” This same condition is amplified a 1000X with Protestants and Catholics.
Catholicism has a rich but very precise vocabulary that is not readily translatable to the English vernacular or even fully comprehensible in the context of modern American culture.
Far too often these "discussions" devolve into a fight over the ownership of the language and the definition of terms in which non-Catholics insist that Catholics abandon Catholic definitions and join them in condemning Catholicism based only on secular language. Even those with dubious claims of being ex-Catholics fail to recognize or acknowledge Catholic language.
For example, when we Catholics explain what we mean by veneration and the response is "No you don't" is there really any point of further discussion?
Nah, not much. We don't fall for the RCC double speak.
