If you're saying that we all have ingrained ways of thinking that we learn from somewhere, then you're stating a truism. And yet people change, and societies change. The pilgrims went to America and set up a social system that draws much from Europe and yet has ended up different, a quite distinct variant of Western culture. But to see the Unabomber as at the core of that American society is absurd. His strand of anarcho-primitivism is there, but right at the margins, not at the core. The technological capitalism he opposes is far more what America is about.
