Apples and oranges comparison. "Hail Marys" contradict SBC theology. The Lord's Prayer contradicts neither, therefore, it's a false comparison.
The KJV by definition contradicts Catholic theology, and yet many Southern Baptists want that version to be taught in public schools, and they want it to be taught as the "official version", in regards to the ordering of books and all, and that also contradicts with Catholic theology
It's not a false comparison.
