The foundational document of this country - the declaration of independence - states that individuals have inherent inalienable rights (endowed in them by nature, their creator, or God - take your pick) and that such rights are not created or granted by the government, but rather that men create forms of government to ensure that individuals may freely exercise those inherent pre-existing rights. And that when such governments become destructive to those ends then it is the right and duty of the people to alter or abolish such government.
"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, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--"
One may agree or disagree with the propositions expressed but the meaning and intent of the foundational document of our nations founding is clear - that our rights do not come from a government or a constitution, or a bill of rights - those are merely the mechanisms used to imperfectly attempt to allow individuals to live free and to exercise their pre-existing creator given/god given/natural rights.
