Subjective Morality?

[brewer]

Nope. There's the catch.
I cannot make objective moral determinations. I cannot make anything objective at all. Nobody can.

I can interpret it and analyze it. And, just like in harder science, I have to be a bit distrustful about all observations, but ultimately the current moral theories (specific laws, not meta about it) are presumably taking into account the largest body of information and are the best conclusion given the data/reasoning. Just like we can say people were objectively wrong about the sun orbiting earth, we can say people were objectively immoral to do certain actions -- we don't KNOW that the sun doesn't orbit the earth, I've never personally stood outside, being stationary, and observed that it does, but we have so much evidence that it's pointless to question at this point. Nevertheless, we are still observing an objective situation, even if not absolutely reliably.

Unless, of course, morality is subjective, in which case I can make all the subjective moral determinations I want

Who is the "we" you keep referring to?

Observation of the sun has nothing to do with morals. Position fail. 

If the observation/observer of the moral situation is not reliable then it's subjective. 

Curious, what is your position on abortion?
