Yet another weird post, I have no idea what you just posted.
Jehovahs Witness, like Mormonism, is considered non-Christian by Catholics, not Protestant Christian.
Here's how I did read it as meaning:
"Jehovahs Witness, like Mormonism, is considered non-Christian by Catholics, not (by) Protestant Christian(s)."
I now know that's not what you had in mind so of course, my response sounded weird to you.
But for anyone who thinks JWs are denominated as "Christian," no -- they are not classed with other non-Biblical "Christians" like "The Church of Jesus Christ of Latter Day Saints" (= LDS = Mormon) or "The Unification Church" (= Sun Myung Moon = Moonies).
I misunderstood your post.
