The Lost One
impossible. Leroy made no error of logic. None at all.
Aside from my days at universities with applied science and some maths that goes with them, particularly on logic for computer science, eg the Boolean logic, AND, NAND, OR, NOR, etc, I don’t have any other formal education in logic. So I have to admit, I am no expert.
But if i can see the very obvious errors that you and @leroy have made, logic or otherwise, then your logical reasoning are even worse than mine.
