Why this childish obsession with objectiveness? Morality is the base for law, clearly it's part of the discussion and they should be held up against each other, so one can see if the law matches up with the morals we as a society agree upon.
All you do is argue about fallacies, it's completely substanceless and frankly, uninteresting as fuck. If you aren't going to actively try to understand people you talk to, I see no further reason to engage you.
