Faithful to what?
Fringe relative to what?
Your question suggests a particular perspective that, from a different perspective, might be seen as 'fringe'.
What matters is how we live together in safe, sustainable communities, for which society developed rules of conduct we call morality.
We can all live good and moral lives whether we are Christians, Jews, Muslims, atheists, Buddhists, pagans, wiccans ... or anything else. There is nothing 'fringe' about living together in peace and mutual respect.
