So do you feel that it is a politically neutral choice for an employer to decide that the health insurance they sponsor for employees cannot be used to cover an abortion?
Nobody's claiming perfect political neutrality. The claim is that it's bad for companies to get political in unnecessary ways. Inasmuch as Hobby Lobby decided to push their politics and religion on their employees via their healthcare package, then we shouldn't be surprised at the result.
Then it's worth noting that it is easier for a person to change which employer they work for than a business owner to change which government creates laws that apply to their business.
I accept, though, that corporations are artificial constructs that exist (ostensibly) to benefit humans, and therefore placing restrictions and duties on corporations is inherently preferable to placing them on humans themselves.
