I'm pretty sure my ancestors did not work their whole lives for me to spurn human progress and voluntarily roll back to a 17th-century standard of living. Especially not at the request of a totalitarian religion spinning lies and preying on superstitious, ignorant dolts. In my observations, people fervently into "green" are people who need to believe they "make a difference" for the planet because otherwise their lives are completely empty. They also seem to have slept through math classes, and taken history after all the white men who built America--bridges, canals, railroads, factories, dams, Menlo Park--got stripped out.
My maternal ancestors would be especially angry if I eschewed the technological developments that allow beer to be imported from Germany and kept cold until can sit down to enjoy it after a long day of not scrubbing my laundry on a board and not kneading my own bread over a stove fired by wood I did not have to split. Who am I to let them down?
