Here is an insightful slashdotter
on SUV bashing:

It’s nothing more than guilt-ridden scapegoating.

Even the most ecologically correct American liberal lives a life of unparalleled luxury and ease, fueled by cheap energy, and uses up the Earth’s resources by orders of magnitude more than an African villager.

Can you imagine how comical it would seem to a man who has never ridden in a motor vehicle, to see Volvo and Prius owners looking down their noses at Hummer owners? The guy in Birkenstocks, whose footprint on nature is fifty times bigger than the villager’s, sneers at the guy in cowboy boots whose footprint is sixty times greater.

Same goes for Europe vs. America. If the American way of life is unsustainable, so is the European, differing only by a relatively minor degree. It may help the bien-pensant European Left feel better about its own hypocrisy by saying “Look! The Amis are worse!” But it hardly solves the problem.

Unless you are already living off the grid, growing all your own food, and never traveling farther from your home than you can walk, you have no moral standing to criticize my choice of vehicles.
