Suppose I come up to you and claimed evolution is true. Perhaps you believe me right away, or perhaps you want to make up your own mind; after all, lots of people tell you things that don’t turn out to be true. Go ahead and do that, I tell you, but if you arrive at any other conclusion besides mine, I’m going to throw you in jail, where you’ll rot for the rest of your life.
Most people would immediately see the problem here. Have I in fact allowed you the luxury of reason to investigate and believe my claim? No, I haven’t, because I’ve really only one given you one choice, and that’s to simply accept the claim that evolution is true. Even providing you with what I consider rock-solid proof of evolution doesn’t alter the calculus in any way. When I threaten you, I automatically remove reason as an allowable means to accepting my claim. I’ve in effect determined your choice. If you were truly free to exercise reason, I would have to accept its outcome no matter what, even if I considered you gravely mistaken. Punishment for arriving at a wrong conclusion turns reason into a thought-crime.
So when believers like Christians or Muslims contend their faiths are based on reason, one may simply object that this can’t be so because their god in fact doesn’t allow it. Using reason to arrive at any other belief than the correct one will earn you an eternity in hell. Thus, reason is in reality an evil to be avoided, as Martin Luther concluded a long time ago. Blind, unquestioning, and unexamined belief is what the theist’s retributive god truly desires, not a belief grounded in reason.

I’ve already expressed my views on why any religion that preaches hellfire is pure foolishness, but I like this objection as well.
Hell was invented to eliminate the possibility of rational decision-making, and any religion that relies on the concept of eternal hellfire to keep people from asking logical questions and using reason to determine the answers should be abandoned and ridiculed for what it really is. Nonsense.
