Well, they're ignoring the most important principle of all these days: That the right to life is God-given and inalienable.
Add to that the various ways they're ignoring other important inalienable rights that are spelled out in the Bill of Rights. One example would be the breach of the First Amendment right to free political speech represented by so-called 'campaign finance reform'. There are others.
