How can a Christian reject part of the Bible and still call themselves a Christian?

Sounds like you're having your cake and eating it.

If judges have value, then why don't you value them?

Still positioning, still failing.  Is my participation required?

I don;t value your divine judge.  I made that clear by specifically referencing the differences between a self appointed celestial busybody with no purchase on any human being..and a judge in a court of law.  This is, as it was when you began, a waste of our time in any case, since law =/= morality.  If you're incapable of or unwilling to provide the only thing required of you in this conversation - a justification for divine moral authority..then save us both the time and just say so.  

Babbling endlessly about our legal system won't and can't approach that subject, since they're not the same subject.  It's just irritatingly dishonest.

Law comes from morality, at least philosophically speaking. When push comes to shove, I actually identify as a contractualist (as opposed to Kantian ethics). In a nutshell, something is a moral rule only if no one has a legitimate objection to it, with objections needing to address why/why not someone's wellbeing is being violated. This mode of thinking captures the essence of debate, in which a conclusion is assumed once no one has a reasonable objection left to say. And if there's no objections, then to my mind it seems like that particular rule makes for a good law - something to be upheld globally.
