Divisiveness was already there; in fact, divisiveness was abound plenty when people were arguing for or against certain libertarian and/or anarchist authors. Blaming the left-libertarians can however further it, just as much as blaming right-libertarians does as well.
Frankly, all they have done is apply libertarianism & anarchism into different areas in an effort to address what they perceive as problems with past libertarian and/or anarchistic thought. (A bit unrelated, but I was reminded of the furthering of such thought this morning regarding this: http://www.blackoakmedia.org/BlackOakPresents/Black_Oak_Presents-_Autumn_2008.pdf; “Notes Towards A Manifesto of Paleo-Anarchism”, pg. 7)
The efforts to further develop the libertarian and/or anarchistic philosophies unavoidable creates allegiances & loyalties to certain ideas and schools within, imo. The fact that elitism (and a focus on labels as tools) still exists in humans, regardless of a community’s political thought, makes things that much more complicated & messy; sometimes as a given, and sometimes unnecessarily.
I do agree that the eagerness of some within a political school to set themselves apart from others doesn’t help unity if this within a larger school of thought, but neither is assuming that all left-libertarians (in this case) do so. Frankly, I’m sick of using the left & right prefixes, & i think that whatever the left-libertarianism regarded as an increasingly “bad” Rightist influence was not Right but more generally a Statist Conservative influence.
Individuality & community are not necessarily opposite ends; would not “right”-libertarians regard the family as an increasingly more important feature of society if & when The State falls? Would not “left”-libertarians regard the invidividual role as increasingly more important if & when the state falls?
Wasn’t there more or less a type of class warfare going on regarding Statists & Anti-Statists?
