We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights... - The Declaration of Independence
The Constitution itself never mentions the word "god" nor does it say anything about the Christian faith. Religious people have argued though that the first amendment doesn't necessarily mean a complete "freedom from religion" and that the so-called "wall of separation of church and state" was just a quote from a letter by Thomas Jefferson and not legally binding.
These same people use the above quote from the Declaration as justification for a lot of things, including the slow infringement of religion onto the public square. They argue that "Creator" is god, so the founders believed there is a god and thus there should be abortion restrictions and any other faith-based laws they choose.
Well, what if a legal person's Creator is a corporate charter issued by a state?
The Citizens United decision reaffirms the random note added to the top of the Supreme Court case Santa Clara County v. Southern Pacific Railroad, and says that corporations as legal persons have rights too. But from where are their rights derived? The Declaration wasn't written for "citizens" since the new country wasn't even formed yet. Those inalienable rights endowed by our Creator belong to persons, not citizens.
Want to really make Republicans' heads spin? Have Democrats author a resolution saying something like the "Creator" mentioned in the Declaration refers specifically to God, or reaffirming the Declaration's point that all our rights are derived from our Creator (and thus not a corporation.) They won't know how to vote on that. If they vote that there is a God they're saying that corporations can't be legal persons with legal rights. I doubt God is worried about granting inalienable rights to corporations.
We should make the point that this decision essentially cancels out God. There is no need for a Creator that is a God to grant us inalienable rights if we give corporate charters the ability to give those rights.
And play god.
This decision allows states to permit corporate charters all over the country and be their own Gods. Endowing their creations with inalienable rights.
There's no need for God anymore, apparently.
