Unfortunately, the Declaration of Independence carries no legal weight.
The Founders thought those rights stated in the Declaration to be self evident. Went so far as to call them 'truths'. And noted that when governments become destructive of those ends, it was within the rights of those so governed to change that government. They felt that strongly about that which you claim has 'no legal weight' that they pledged lives and fortunes in a desperate gamble and rebelled against the strongest nation on the planet.
Only to have those 'truths' dismissed as 'having no legal weight'. The very foundations of the nation has 'no legal weight' to some on this very board, and to those vultures in black robes that infest our 'legal' system.
I'm stunned.
