The odd thing for me about the deep stupidity of the objective morality claim is that those who assert it really seem not to see the qualitative difference between it and values that actually are objectively the case. Ask enough people whether murder is wrong and eventually you'll find someone who says, "no, it's fine". That's his opinion and that's his morality.
Now try asking lots of people what'll happen if they jump out of a tenth storey window. Eventually you'll find someone who'll say, "I'll float gently to the ground" but you could test his claim readily enough and find it to be wrong.
What objective test would anyone propose I wonder for subjective opinions about morality?
However much dust they throw to obscure it, that's still their central problem: bridging the gap from the subjective to the objective.
