The author of this article only obfuscates the facts. America was founded on the basis of religious freedoms. Ours is the only country where these freedoms are guaranteed. As such, we recognize the right of others to believe as they believe, but we are permitted free open discussions on the differences too.
What this want to do is force all to CONDONE other beliefs rather than tolerate. Big difference.
It is one thing to acknowledge our religious divisions, another to celebrate them. Tribalism of any sort tends toward conflict and toward a law that subordinates the truth to expedience.
