Let me remind you of something:
“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 to 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; [...]”
Note that they [the founders] admit, up front, that they are instituting/organizing a new government that best seems to secure the liberties of its people; they also state that the governments “long established” shouldn’t be changed lightly, the converse being that young-governments will have to be changed in order to resolve mistakes & oversights, most especially in relation to securing those rights.
So if you want to rebel and issue your own declaration explaining why then have at it.
