Ask ... and they'll give you reasons.

Yes, but in the real world, when a religious demand conflicts with something people really believe, it can go either way. Some people will find reasons that justify the demand. But some will find reasons that go in the other direction--instead of reasons why the religion demands some absurd thing, they'd give reasons as to why the religion's obvious demand really isn't a demand at all. Where are the people saying that the prohibition on murder is meant metaphorically, or only means "you shouldn't commit murders in this specific situation that only existed thousands of years ago"? For that matter, where are the people saying "sure, my religion says we shouldn't murder, but I have no right to impose that on nonbelievers by force of law", in the same way that they might say that about other mortal sins?
