There is ultimately no other source of morality except a creator.
This is a bald assertion - why?
The atheist view is variable,
So? Unanimity doesn't connote correctness (and that's assuming that correctness is even
possible).
The Christian view is imple: life's goal is conformity with the divine, so that anything that detracts from that is plausibly immoral.
Simplicity doesn't connote correctness, either.
But what is rape? All you've done is offload the definition of what is moral onto what is rape.
Sexual activity where not all participants are consenting.
The dictionary would have told you as much.
What happens if a woman voluntarily disrobes in the presence of a man not belonging to a recognized profession? Should allegations of rape be entertained?
No - no sexual contact has taken place.
But laws
are in place for public exposure, which is a separate charge.
Then you would find the whole penal system immoral per se.
No, because I consider that harm to be
justified.
My morality is defined in terms of intent to cause
unjustified harm.
Meaningless. What is the standard for rape?
"Do all participants consent?"
Not all allegations can be proven or objectively justified.
Correct - so?
If I do something to you that you can't prove in court, that does not affect the morality of what I did.
You concur that atheist "morality" admits of no fixed standard,
No.
Each individual atheist's standard is fixed.
I see no morality that is
not opinionated.
"What my god says is moral, is moral" is opinion, until it is proven, and not merely asserted.
and radically different from theist morality.
Again, no - you and I likely agree on the vast majority of moral questions.
The only difference is that I
think, and you
read.
