My views on objective morality

[Catholic_Lady]

Jor, it revolves around our belief that life is sacred and that we all have inherent, God given human rights that ought to be respected.

That is what you believe now, but why is that privileged over what people believed then?  You've essentially just said that your current view is superior because you believe it is superior.  Besides being the hallmark of subjective morality, that's a circular justification for believing that the prior generations' morals are inferior.  In other words, that's no justification at all.  Try again.

You're right, I do believe being against slavery and genocide is morally superior to being for it. If that means I think my morals are better than pre civil war America, Isis, and Nazism, then so be it I suppose. I have no problem with that. If I didn't believe they were superior, they wouldn't be my morals lol. 

With that being said, I think we have always had an inherent understanding that human life has value. The rationalization often was to say that certain groups of people weren't really fully human. That's partially how a lot of civilizations have justified genocide or enslavement. Now a days, many of us justify abortion with the same rationale - that a human being in the womb is not really human. I think in the future people will look back on it the same way we look back on slavery and the slaughtering of the indians. Of course, that won't begin to happen until we discover a different way of dealing with unwanted pregnancies that don't involve having to kill the fetus. We have a tendency to rationalize a lot of things when committing them is convenient or beneficial to us.
