Health and healthcare can be extremely personal.
Individuals choose to tightly control their healthcare information by limiting access to themselves and their healthcare providers. As recently as 1996, the federal government concurred with individual privacy rights for such information and enacted privacy laws.
Personal issues pertaining to aspects of health may be influenced by private, familial or moral beliefs about humanity and the sanctity of the human body.
Personal and social beliefs are strongly affected by individual theology and/or personal religion and are therefore exempt from federal authority by the first amendment of the Constitution. The First Amendment declares personal theology to be outside federal jurisdiction.
The Affordable Care Act (ACA) makes a noble attempt to provide healthcare insurance to those in need; however, parts of the ACA infringe upon personal theology.
A one-size-fits-all insurance plan cannot guarantee adequate healthcare or protection of the Constitutional right to religious (theological) freedom.
Indeed, the ACA is, by its very nature, a violation of the first amendment!
