There are a couple of articles I wanted to recommend, that are thoughtful, maintain the biblical stance on these issues, and suggest ways to connect with love and respect to those who think and believe differently.

There is also a good article here, for those who are tempted to despair:

And remember, “Supreme” is a relative term.
