A poll I conducted awhile back.

One gratifying aspect of our rise to some prominence is that, for the first time in my memory, we, ‘our side,’ had captured a crucial word from the enemy. Other words, such as ‘liberal,’ had been originally identified with laissez-faire libertarians, but had been captured by left-wing statists, forcing us in the 1940s to call ourselves rather feebly ‘true’ or ‘classical’ liberals. ‘Libertarians,’ in contrast, had long been simply a polite word for left-wing anarchists, that is for anti-private property anarchists, either of the communist or syndicalist variety. But now we had taken it over, and more properly from the view of etymology; since we were proponents of individual liberty and therefore of the individual’s right to his property.
