Answer: I don't know that we do differ in the big picture. I'm a fan of anarcho-syndicalism, and I have no problem with libertarian socialism, from what I can see of the two concepts.
Anarcho-syndicalism seems to be a manifestation of Gandhian unionization. I think Gandhian unions are the solution to the current minimum wage issue in America and will probably be the mechanism to abolish the state conception of life. And in a stateless society, as I seek to promote, there are no laws to prevent moral unions. Dr. Chomsky, from our exchanges, does not seem well versed in Gandhian Philosophy, as he has expressed in the past that my Gandhian questions are beyond his scope of expertise, but we are talking about the same elephant, I can tell. There are a world of ideas he holds that will forever remain beyond mine, so I feel special to know something he doesn't, even if we are covering the same animal with different words.
Libertarian Socialism to me is the free will choice to live in a commune without a badge and a gun pointed at you to live in the state commune/ forced collectivism. I'm happy for people who wish to live in such a way. There are many moral types of communism and socialism in the world, so I have zero problem with his endorsement.
I am an Anti-Marxist because of its violence, and I think Dr. Chomsky sees this, as well.
