Central apologetic argument: if Smith lied about one thing as a prophet, he is a false prophet — and the evidence proves he lied

Mike draws the logical conclusion: if Joseph Smith fabricated his ability to translate Egyptian as a divinely-given gift, then there is no 'possible way this guy's a prophet.' The fraud in the Book of Abraham — falsely claiming to translate divine revelation from God — means the entire foundation of Mormonism, including all of Smith's new revelation, is built on a lie. The only logical conclusion, Mike says, is that Smith was not a prophet.
