One last thing before I go. Jenny, why do you continue to appeal to history? Is it that your "philosophy" is lacking? Why do you need history to prove your points, when "logic" and "reason" should do the trick?
Morality is not a product of deductive logic. Morality - as a consistent set of principles to use when evaluating the actions of others & yourself - is a tool we use to maximize human flourishing. As such, the optimal moral systems are discovered using a combination of observation, induction, hypothesis, deduction, and observation again.
For the most part, nobody comes up with successful moral laws through deduction alone. We have to discover them.
