[L]iberal intolerance represents not the self-undermining of liberalism, but a fulfillment of its essential nature. When a chrysalis shelters an insect that later bursts forth from it and leaves it shattered, the chrysalis has in fact fulfilled its true and predetermined end. Liberalism of the purportedly tolerant sort is to militant progressivism as the chrysalis is to the hideous insect.
