The word "guarantee" does not mean to give. It simply means to protect, and yes, the purpose of the BOR was to identify and provide guarantees for the protection of those rights.
The Right existed prior to the Bill of Rights, all the BoR did was to enumerate them and restrict government from trying to eradicate God granted rights.
I agree, but I doubt God determined that machine guns were God given rights. I think perhaps He thought a tad larger and that He would have said "A person has a right to self-defense".
And BTW, I have never said that the BOR gave any rights to anyone. Either they are natural or God given rights or they are simply freedoms.
But for some here, seeing the freedoms in Iraq today must bring great hope, because everyone who belongs to any of the several hundred militias and other groups have every weapon money can buy. Seems to work well for them. I'm sure that's what our Creator had in mind...
I don't see where we disagree at all.
