Arnold Kling sets out the Libertarian Basics as a response to Austin Bramwell's comment that "What libertarians do not have, however, is a comprehensive argument for their ideology."
From a libertarian perspective, if I choose to give my money to someone perceived as less fortunate, that is my business. If you choose to give my money to someone perceived as less fortunate, that is theft. Libertarians see redistribution as theft, no different than if a criminal gang seized property for purposes of "redistribution."
Perhaps our thieving, meddlesome politicians aiming to correct "societal wrongs" through reservations, bans, censorship & licensing, should read this, and think about it!
