You seem to be saying that secular morality is as delusional as the religious kind, or that religious morality isn't so bad, so there's no need to choose between the two.
For me the issue isn't that choice as much as the need to not fool ourselves so much. The question is whether morality is compatible with existential authenticity, intellectual integrity, late-modern maturity, and so forth. If theism isn't viable, theistic morality would be a ruse, an anachronism. And secularists have trouble justifying morality on atheistic grounds, without committing the naturalistic fallacy. It's a problematic subject, as I argue elsewhere, which is why I aim to rethink secular morality in aesthetic terms.
