if a insane man believed he had to kill babies cause it was a divine act of love, then would it be unreasonable? you wouldn't let a dangerously mentally ill person roam public areas ? to me the same principle applies to religion and that's why it should be forced just as a mass murderer should be imprisoned to protect the public, its more reasonable than you might think. though i totally agree the chances of it happening are slim to none. but then again who can predict the far future, maybe a event of cosmic proportions will wipe all our species out, and religion wont be an issue anymore hurray! its not impossible that this can happen. in fact religion itself could be a source of the death of our species, with all their holy nuclear bombs
, and they could decorate them with symbols of their religion
that would be nice.
