Fortunately, you can't CONVICT on belief alone.
Absolutely right, in theory. In practice, it's a depressingly regular occurrence.
(Which is sort of off topic - and I completely back your point that belief can never be used as a basis for harming another person in any way whatsoever.)
Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
