What exactly does it mean to be a “left-wing libertarian?”

[FEMA Camp Administrator]

The concept of the elusive left-libertarian is something that grinds my gears on a continual basis - as Baptista indicated, the "lib left" quadrant is basically just standard left-liberal/progressive in most contexts (assuming the up-down scale is "social issues" and not "preferred political system"). Conversely, upper-right/auth-right is standard conservatism. It is for this reason that I have said the political compass should be rotated 45 degrees to the right (so as to be a diamond with authoritarianism of all stripes in the upper quadrant).

As stated variously above, actual "left-wing libertarians" (as in, seen as deviating from standard left-liberal or progressive politics) could be anything from Jerry-Brown-in-the-70s-esque "neoliberals", to Berners who are libertarian only on traditional left-wing grounds, to anarchists who think that power doesn't abhor a vacuum.
