Ok; I've just never heard of that tactic in debating a subject.
And I have not hear your "same-to-you-but-more-of-it" request for references since third grade.
And it is not opinion. It is personal knowledge. In fact, it is straight forward logic. "Mormons teach - - -" followed by "I am a Mormon and I do not teach that." I guess you aren't familiar with logic?
Oh, and I still haven't seen the references on the original claim.
Neither have I.
Perhaps it, too, is personal knowledge.
I guess we'll have to wait for the data to be forth coming.
I guess this COULD be logic; but it sounds more like a testimony to me; from a True Scotsman.
