We need to restart the conversation though, by including the discussion of secular morals which can be embraced by all religions and the non-religious alike. All these conversations seem to be about is which brand of Christianity do people prefer. There are many Americans who are not Christian, yet this "conversation" about moral values is nearly always framed in a Christian American nationalist context.

We used to call the overarching basic premise of our moral values in the US "The Golden Rule". It didn't have god in it, just "do unto others as you would have them do unto you."

It is a Christian quote, I know. But the concept is the best place to start: the standard of the way we care for others should be the same standard of the way we wish to be cared for ourselves by others.
