Not so. ColorCountry refers to herself as a "born-again" Mormon. I don't refer to her as an "apostate." I'm sure I don't agree with her on everything; that doesn't mean that I issue some blanket statement on her (like the LDS "scripture" does) calling her an "apostate."
Show me where Catholics label Baptists as apostates. (I've worked and rubbed shoulders with plenty of Catholics; none have ever considered Protestants as "apostates"). [Straw man on your part]
...all Jewish faithful label all Christians as of an apostate faith.
Technically, an "apostate" is one who has left the faith. So if Jewish faithful never considered Christians to be of of the faith to begin with, then, no, they don't label us as such. [How many strikes, again, does it take to strike out?]
Additionally, you said ALL Jewish faithful. There, you are doubly wrong, for thousands of Messianic Jews are among those "Jewish faithful"--and they don't consider us as "apostates," either. (If you want a precise answer, just contact Jews for Jesus)
So when can we expect just one time for you to admit that you are wrong?
Lets face it. If anyone thinks they are right, they automatically think others are wrong. BIG DEAL.
We all have certain "blinders" on. That doesn't mean that just because the church filter I see through = all other church filters are wrong. If we agree on the essentials, then the rest is secondary. (Just like if I agree on the essentials with my spouse, then the rest is secondary. Unity does not = Unanimity)
Face it, there are some "secondary" things where folks can agree to disagree. (If the two believe contradictory things, both can't be right and in fact, both may be wrong).
Finally, LDS "scripture" takes blanket condemnation of all non-members to the nth degree. For example, I can believe that LDS are "right" on some things...losing your salvation, for example. I don't label every creed they adhere to as "an abomination before the Lord." Nor do I call all their "professors as corrupt."
Yet, when you reverse this, LDS cannot say the same thing.
