The Declaration did not "grant" us anything. In it's own words.
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.
So, the government was created, by the Declaration and later "altered" by the Constitution, to "secure these rights". They were not granted or created by the Declaration, The Constitution or even the Bill of Rights. The later attempts to protect them, but not create them.
I agree. It was not granted until we fought and bled for it. Thnks for the agreement on timelines. Ask first for freedom, if not granted, fight for it.
