I think you all might get a laugh out of the thin veneer of an attack as critique, but I think you all had the right to take a look and come up with your own responses here and on the comments section of the video linked here.
"The power of liberty going forward is in decentralization. Not in leaders, but in decentralized activism. In a market process." -- liberty student
When someone evokes the "scientific method", I take it on par with a very poorly educated (with regards to their own doctrine) Christian evoking divine revelation.
Freedom of markets is positively correlated with the degree of evolution in any society...
The problem I have with their critique is that by their logical conclusion then all philosophies are religion and that would include empiricism and positivism (as both still use some axioms to make their claims). So, I find the argument at best naive, and at worse something akin to flinging pooh at someone.
