Hell ticks me off. It's unprovable since it supposedly happens after death. No one's ever come back from there. So it really irks me because various churches use it to basically coerce people. The first time I heard the argument, "Well you might as well believe in Jesus because if it's not true, you have nothing to lose. But if it is true and you didn't believe, man wouldn't you be sorry when you found yourself burning in hell for not believing." I got so mad. It's a gangster's proposition that could be used to strongarm anyone into anything unprovable. In my opinion.
