if you present your best case for LDS, and no one here considers it persuasive enough to convert to LDS,

Other people understand this differently (e.g. I can not speak to calcsam) but as far as I am concerned the goal should never be to persuade anyone to be LDS but to present the message, let them know that you know it is true, and invite them to find out for themselves if it is true, then answer any questions they may have. Then it is to let the Spirit do whatever else it will to bring about a conversion.
