There seems to be some strange notion that to recognize the fact that our rights are a consequence of our humanity, acknowledged and codified by Constitutional case law, and not the ‘creation’ of a non-existent deity, that our civil liberties are somehow ‘illegitimate.’
It goes without saying that this is ignorant idiocy.
Indeed, the fact that our rights are recognized as a result of human struggle, where men have fought and died for their rights against ignorance, hate, and intolerance, makes our rights that much more valuable and legitimate, as opposed to something just ‘given’ to us by an imagined god.
There seems to be some confusion that the idiots define the debate.
The initial question in this thread was what rights come from nature[?]. There are always going to be idiots that insist that God is the only possible source of rights, just like there are going to be idiots that, since we cannot prove God exists, that negates the concept of natural rights entirely.
We fight for those rights because it is our right to fight for them regardless of their actual source. The struggle for the rights that legitimately come from government is just as bitter and hard fought as the one for natural rights.
