It’s true, we have no natural rights. A right cannot be taken from you. We have given ourselves rights under our Constitution but they are constructs of human minds. People say you have a right to life. Try walking through South Chicago almost any balmy night, or else try living in Kiev under Russian missile attacks targeting hospitals and civilian housing areas. I am sure the so-called grizzly man protested to the bear as it was attacking and eating him.
Your right to liberty can be curtailed by government quite easily. Think of anything you would call a right and somewhere on this earth it is being violated by governments, gangs, individuals and the cosmos itself if an asteroid lands on your county. Tornados and hurricanes, earthquakes and wildfires will not listen to your protests. Other humans have proven to be just as indifferent. The holocaust, the Rwandan genocides, what Russia is doing in Ukraine, what the British did when they invented the concentration camp, slavery of all sorts for millennia.
No, the only “rights” we possess is what we as individuals or groups can defend. Which is why our Second Amendment is so important. It protects all the other rights we have claimed for ourselves here in the USA. It protects them from strangers, gangs, other groups and governments; including our own.
