Ethics aren't made - period.
It is found in the logical operation of the immutable nature of all things..
I agre, but then I don't see how having no religion would mean that legislators make our ethics?
A subjective morality is a contradiction.
Morality is a measure of good and evil. Any measure divorced from a fixed standard is an indeterminate thing - hence lacking both form and substance.
How do you measure emotions? How do you measure beauty? You know something is more beautiful than something else, or that something makes you happy or it does not, but it is subjective and does not have a specific scale and from one person to the next it does not make the opinion any less valid.
You and me liking different music for example does not mean that there is no standard, it is a personal standard.
And by the same approach, something one society finds acceptable another society may not - it is subjective to their beliefs and moral standards that have been forged over generations.
