If your views by definition are enlightened and progressive, why should you bother understanding those of the other side?
I find the criticism totally accurate. The main theme among Democrats is that Conservatives are stupid, but when it comes to him suggesting that Republicans have good arguments to make and I think the do, the ones the author gives as examples are dumber than shit. i think he does a poor job of making his case but then, like he predicted, his arguments just seem plane dumb to me.
The strengths I think Conservatives have over liberals is that they take more factors into account as important moral values. But just like the author here, the way they see those values looks plain dumb to me. What possible good is it to hold values and not know what they are in reality? Take respect for authority. Vital for human survival. Thinking Trump is a positive example of respectable authority, insanity.
