I'm a newbie, and I strongly suspect I should not post on this topic.
However, there are some apparent contradictions between extropian and libertarian philosophies, at least as I understand them, and I have read the reading list.
Also, I might be a pretty rare bird, since I espoused objectivist and libertarian principles for almost twenty years, and I now believe I have reasonable arguments and evidence against some extreme claims of both objectivists and anarcho-syndicalist libertarians. I would be interested to see if these reasons make sense to any of you.
Should I stay out of this? I have no interest in boring or inflaming the list members.
