What’s the problem with all of this? The answer is obvious: once you redefine rights to mean anything you want—and replacing rights with the “common good” does just that—rights no longer have any meaning, and you lose all protection. There is no way to ban hate speech without granting the government the power to destroy free speech. You cannot mandate “economic fairness” without giving the government the power to destroy entrepreneurship. You cannot mandate racial tolerance without granting the government the power to destroy freedom of association. There are costs to rights.
