I've been listening to this podcast every week for several months, and I've decided to stop. It's okay if you want to listen to the libertarian perspective, but it doesn't seem to go beyond talking points and doesn't have enough depth for me. After each lecture, there are never any challenging questions from the host or the audience. I know that libertarians want a much smaller government. So each week, why don't they offer a lecture on a specific topic and provide some real details about how smaller government would work, and also address any counterarguments and concerns?
I believe that the libertarian movement has been a negligible political force because it rarely gets beyond its own nice-sounding superficial talking points, and when it does, you hear extremists like Rand Paul saying that private businesses should be able to discriminate against anyone for any reason, and that the market's "invisible hand" will eventually force people to be decent. I suppose that if you happen to belong to a non-oppressed group - as Rand Paul does - "eventually" isn't so bad. :-)
On a positive note, anyone not familiar with libertarian talking points could learn from these podcasts, and the audio quality is very good.
