And where, pray tell, does the "preacher" find the persons to run and administer the government who are without "sin"? Why is it that he believes some imperfect persons in positions of power in government will make better or more virtuous decisions than all the other imperfect persons they control?
Exactly!
That is the core, irreconcilable flaw at the heart of all liberalism, and it renders the entire project irredeemably false. Liberalism simply cannot answer that question, which means that the sole justification for their actions and their policies ends up being naked aggression, nothing more, nothing less - certainly not the highminded rationality liberals have deluded themselves into believing they still possess.
Precious few liberals/leftists are willing to admit as much; Mao was one of the few exceptions, who more or less admitted that all the flowery language about rights and justice and merit were mere window-dressing, meant to camoflage the ugly truth that, for communism, socialism, and all species of thought that are similar to liberalism, "power flows from the barrel of a gun."
Thank you for you concise summary!
America's Founders, understanding the imperfection of human nature and the tendency to abuse power, framed a government of enumerated, separated, limited, checked, and balanced powers to curb that tendency.
What's more, the document that framed the government demanded in Article V that only the People, through the Constitution's own prescribed process, could alter the limits and curbs on that power.
Those, like Wallis, who look to imperfect persons, elected or appointed to positions of power in government, to be the arbiters of rights and liberties, are misguided at best. At worst, they find status and prominence for themselves by thinking they are part of the "political power elite."
