Decolonise colons!
Yep, the term 'left-libertarian' has tended to be used by individuals rather than groups. I suppose, in some cases, the rationale was to distance themselves (and their work) from the perceived neagtive connotations of the 'A' word in order to attract a wider audience?
Definitely some truth in that, though not so much about attracting an audience so much as not immediately alienating people.
Agree with butchers about how the term libertarianism has been gifted to the right. To some extent I think that's deliberate.
