Except that something is moral whether any being cares about morality or not, just like something is prime regardless of whether or not anyone cares about primality.
And what happens when you plug in MrMinds claim that there are multiple species specific moralities? Doesn't that mean that every action is both moral and immoral from multiple perspective?
I think we've ceased to argue about anything but definitions.
Cut out "morality" and get:
Different species have different sets of values they respond to. Every action is valued according to some such sets fo values and not valued or negatively valued by other sets of values.
You can call any set of values "a" morality if you want, but I think that ceases to refer to what we're talking about when we say something is moral whether anybody values it or not.
