I think PG's a product of his world. He isn't an expert in personality or psychology, so he looks to other tech leaders as thought leaders and independent saviors, and he is regurgitating commonly held views about Left and Right to fit his construct. He does so with extremely scant evidence, because his task is to make a snappy essay, not a coherent theory with strong evidence.
