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

[𝕭𝖆𝖕𝖙𝖎𝖘𝖙𝖆 𝕸𝖎𝖓𝖔𝖑𝖆]

If you call the left half of the political compass "left-wing" and the bottom half of the political compass "libertarian" you get that pretty much anyone who mostly holds redistributist (left-wing) economic views and mostly holds individual-freedom-focused (libertarian) 'social' views is some version of "left-wing libertarian", including a majority of this forum, but that's not a very useful definition, unless we restrict it to the very corner of the quadrant.

Pretty much what Donerail said.

Also, for Heaven's sake, stop stereotyping the auth-left as communists.
