Why Libertarian? Libertarian is the only honest political philosophy. Libertarian is the only reasonably honest political party, pointed toward a fair government, allowing the variety of human experience to flourish — just calling the balls and strikes. All other political parties specify preferred winners and losers.
Why logical? There are extremists in all philosophies. There are perversions of all philosophies. To get it right, one must think it through. The Libertarian Party, being young, is somewhat overrun with youthful exuberance.
