Our American civilization seems to be unwinding right in front of us right now.
Could be.
Could also be that the parts that have been unwinding for decades just got hold of cheap video cameras, and we have the internet.
Instead of parading around their rival's campgrounds waving the heads of their wives and children on pikes, now they post the evidence of their cruelty on Facebook and YouTube.
It is. These are all signs of a civilization in decline. Once it gets going it does not come back.
