" For progressives, the future is not a maze of human uncertainties and unintended consequences. It is a moral choice. To achieve the socially just future requires only that enough people decide to will it. Consequently, it is perfectly consistent for progressives to consider themselves morally and intellectually enlightened, while dismissing their opponents as morally repulsive reactionaries, unworthy of the community of other human beings. "
