Brian, you are so afar afield it's not even funny.
Constitutional rights are NOT rights declared in the Declaration. What you fail to acknowledge is that between the Declaration and the Constitution the country was ruled by the Articles of Confederation, which did not contain the Bill of Rights. The Constitution was not ratified until 1791. The Declaration was written in 1776. There was a lot political wrangling (and a huge failed start...the Articles were a failure) that in the end crafted the Bill of Rights.
In anycase, none of the rights enumerated in the Constitution are unrestricted. Not one of them.
That said, the Constitution unequivocally gives citizens the right to bear arms....and of course, it's been a controversial issue how far that right extends.
In heated political discussions, it's often important to remind ourselves that despite our differences we (american political discoursees) inhabit a very, very narrow political spectrum, historically speaking. No need to get really worked up over very minor differences on regulations..most everyone in the states is a "liberal democrat", historically speaking, and the huge gulf that separates the conservatives and liberals in this country is really a very small difference in governance preferences.
