from ex-mormons, "so and so did x, y, and z, they are hypocrites."

It's our duty to call out that logic and repudiate it strongly. We are all terribly lucky every sin doesn't have a distinct smell like cigarette smoke or liquor breath. If each sin had its own scent, we'd probably hesitate to look twice at someone who comes to church smelling like smoke or **gasp** wore BYU gear while failing to head a prophet's counsel, and NOT A COMMANDMENT.
