So, you bring up a point to a TBM, and they automatically call it an anti-Mormon lie, so you simply tell them it's in their own scriptures, which rocks them back on their heels for a moment.

They catch their breath, and kicking in their moral superiority, say: "Show me where it says...?"

When you DO show them, they whip out excuses and/or their testimony....

Any favorites?

... I've gone through that scenario so many times before it sunk in that a Mormon mind was a closed mind and it was useless.

Now I try and stop myself (not always successful) with the very first step of even bringing up a point.

What works best for me now is, when a Morgbot points out some faith promoting something -- I leave the room (even if I'm their only audience) -- and that sends a better message that sinks in with them more than trying to introduce any sort of logic or reason to the conversation.

Mine was, "Show me where it or any other place that Joseph Smith had sex with any of those polyandry/polygamist wives."

I had to tell them, "Yes we have no diary or letters by any of the women that state, 'Yes I had sex with Joseph Smith'" What we do have is the testimonies of several of Joseph's wives and women in the 1892 Temple Lot case, where in their puritanical Victorian manner the women under oath stated they did have sex with Joseph Smith.

So then I have to find the transcripts and show them. Yet many still won't believe it. So then I have to show them FARMS statement, "We only have proof that J.S. had sex with one of his polyandry wives".

My favorite is the 180 they do.

You: "It says thus-and-so"

Them: "No it doesn't! It doesn't say any such thing. Show me
where it says that."

You show them right where it says that

Them: "Well that was during a very trying time in the Church
when . . ."

They go from claiming it doesn't exist to showing advanced
knowledge of it within less than a minute. Kinda like when the
BBC guy asked Holland about the penalties in the pre-1990
endowment or when the BBC guy asked the "spokesperson" about
the "Strengthening Church Members Committee."
