If I understand you correctly, you are attempting to disprove faith in Mormonism with reasoned argument.
If so, the effort cannot succeed.
If a person has faith in anything unseen, then he/she is more likely to be accommodative and tolerant of others with similar faith, even if the specifics of what is believed are different.
Where are you in all this? Do you believe in things unproven, unprovable and unseen?
