Religion was man's first crack at philosophy. So any sort of moral philosophy prior to modern science is likely to fall under some sort of religion. You don't get a Nobel Prize for figuring that out.
You're missing the obvious point here, which is that the Golden Rule seems to have some sort of corollary in all cultures worldwide, which speaks to it being ingrained in humanity, not dictated from whatever imaginary gods or goddesses. Also, calling Buddhism and Confucianism "religion" is a stretch.
How do you define morality?
You don’t know anything about Buddhism, an incredibly pantheistic and superstitious religion.
You are saying morality is instinctual and evolved.
Talk about imaginary beliefs.
I do like that you have tried to step up your discourse a bit by moving in to the sociobiological.
