It's good to see that someone is recognising that the abortion issue is not a religious one. The fact that religious people have strong pro-life convictions no more limits that position to being a religious one any more than the fact that most religious people believe in marriage, or helping other people. This abortion issue is a civil rights issue.
Many godly (Rom.2:15) atheists know abortion is murder while many godless (apostate) Christians act as if it weren't.
The National Lawyers Association takes the position that the practical effect of the legal connection or relationship between the Declaration and the Constitution is that the Constitution is to be interpreted in the light of the principles set forth in the Declaration.[...] The Preamble introduces and explains the purpose of The U.S. Constitution, and links it to The Declaration of Independence."
The Preface to the United States Code - Annotated states that "this code is the official restatement in convenient form of the general and permanent laws of the United States in force December 7, 1925...." The Preface also states that there is also contained therein a copy of the Declaration of Independence, the Articles of Confederation, the Ordinance of 1787 and the Constitution with Amendments.
