Idaho bill would protect businesses refusing service on religious grounds

In general, a policy of letting business refuse to serve people, or refuse to provide certain health benefits seems like a bad idea.

Sure, this is the whole Catholic anti-abortion thing, but what happens when a Quaker-owned company wants to not pay whatever percentage of income tax goes to the DoD? Is the Catholic Church going to get a privilege that the Society of Friends does not get? That doesn't seem constitutional.
