@Ucantnome, JWs for the most part are not stupid but they are deceived or deluded.
Religion appeals to the emotional aspects of our being often at the expense of the logical. Humans can find emotional drives more powerful than any knowledge of the cosmos which might seem detached or merely abstract... but our feelings are what we live with and what we colour the world with.
It takes some growing up to step outside of a purely emotionally driven life.
