Funny you use the term "dead." And I don't menan ha-ha funny. The previous America you mention may not ever return as it may be too late. And if some semblence of sanity returns it will only be because of a catastrophic event like a MAJOR terrorist attack. And probably not even then.
As much as it may seem at this miserable moment that the Old America is pushing up daisies, has shuffled off this mortal coil, has joined the bleedin’ choir invisible, or is pinin’ for the fjords, I think it still lives and breathes. Among other places, it lives right here on this page.
