"...his new book The Republican Brain, which purports to show that conservatives are, literally by nature, more closed-minded and resistant to change and facts."
That's a non-sequitur for a start, because the Republican Party is not conservative, it's liberal-lite.
As a National Review neocon Goldberg knows all about the liberal mindset. Urging America to go careering round the planet starting wars for abstract concepts, wallowing in permanent revolution and "creative destruction", backing a security state that meddles with citizens' liberties, cheerleading for immigration? The neocons, direct descendants of Trotskyism, are the biggest rapid-reaction utopian junkies of all.
