"birds of a feather flock together" - the more transparent the feather the better.
Self-preferred deceptions do not a happy flock make, nor a self-fulfilling life; deceptions take us in wild and self-destructive directions. By now we should have a common feel for common necessities, and the sense to fly in the direction of a commonly survivable future.
It's within our power to take actions necessary not to be trumped against our better instincts. We need to take such actions in collaboration with each other, with all other. It's the political and right-minded thing to do. Religions should not put us in conflict; to the contrary, they should point is in common direction, toward common enlightenment.
The "feathers" we wear sometimes confuse ourselves and others with respect to the truths intended by our better instincts. Yes, ancient wisdom of all stripes needs to be open to trim its feathers in new-found light.
