I wouldn't. Witnessing, planting seeds for others to harvest, is one thing, but anything beyond that is like trying to help a new member of a congregation get acclimated exclusively by phone. You have to be there in person.
>> Question: Do you believe your leaders or not? If you do, are you not guilty of the very thing you accuse others? [excluding from Christianity and salvation]
To Calvinists, those they presume to exclude are in their opinion not saved and going to burn in hell forever without being able to do anything about it unless it happens that God decided before the foundation of the world to regenerate them at some point. (Help me wordsmith that if it isn't close enough.)
We don't look at it that way. All who repent and turn to Christ in faith will find mercy. Those whom God decides did not have a first chance in this life to hear the Gospel will have a first chance in the Spirit World (as it was for antediluvians in 1 Peter 3:17-20, see also 1 Peter 4:6).
I just posted on another thread where we are being criticized by some of our Jewish friends regarding pre-1995 baptisms for the dead (baptisms by proxy for and in behalf of those who have passed on, effective only if they accept it) of Jewish Holocaust victims who have no LDS descendants.
You can criticize baptism for the dead (see 1 Corinthians 15:29), but you can't at the same time say we are not inclusive.
