Responding to Susan (Hogarth?) at http://knowinghumans.net/2009/01/extra-nolan-chart-dimensions.html :
I wouldn't agree it's divisive to acknowledge, understand, and celebrate the diversity of the principled schools within libertarianism (cf. http://libertarianmajority.net/major-schools-of-libertarianism). Nor should we welcome a faux "unity" built on shared obeisance to the idea of an anarcholibertarian "plumbline" that can measure the degrees, minutes, and seconds of the "deviation" of any particular non-anarchist libertarian.
That is why I say the LP's mission should be to "unite all the voters who seek both more personal liberty and more economic liberty behind the choices available to them (or their representatives) that will most move public policy in a libertarian direction." It's also why I oppose dividing libertarians into multiple parties: http://libertarianintelligence.com/2008/09/why-multiple-freedom-parties-is-dumb.html
