Of course the huge difference is that progressives are concerned about real problems, and the ignorant conservatives are concerned about imaginary enemies and preserving superstition. There's really no comparison with the conservatives completely off the rails from hate-radio, wingnut blogs, and Fox News.
Exactly. progressives are right, conservatives are wrong, and there's absolutely no need to address anyone else's issues because Truth. Which is exactly what the GP was complaining of, but with respect to both extremes.
Meanwhile the people actually involved purchased a hybrid before switching to an SUV, which suggests that they're neither stereotypically conservative nor stereotypically progressive. There's valuable objective information embedded in that problem, yet you want to focus on which of the stereotypes is superior to the other.
Way to miss the point, as well as a shining opportunity to address the real world concerns and behavior of the 'middle.'
