Your last sentence is the danger.<quoted text>
I think Buck was implying that a BELIEF in a deity as the source of rights was significant apart from whether that was true or not, as if without that belief, that we couldn't or wouldn't have had those rights.
My contention was that the words alluding to a god added nothing, and wouldn't convince a Christian who thought he knew his god's will of anything. The Christian god has nothing to do with rights or freedom. It is apparently opposed to the exercise of free will, for which the most harsh penalties imaginable are imposed.
I can envision Christian preachers everywhere objecting strenuously to ideas like gender equality, the freedom to work on the sabbath, and the freedom to blaspheme.
I hear that Mike Huckabee may run for president in 2016.
