Very true. In fact, religious morality is the exact opposite of objective -- it is arbitrary, full of magical exceptions, and not based at all on relevant material fact. Once again, cunticula has it exactly the other way around. Does not surprise me.
I'd argue there's a bias towards equating "morality" with "good". I, too, can't see any way to have morality without a supreme authority. This doesn't mean there's no right and wrong, the responsibility for deciding what is what is simply left to the individual.
