As far as I can tell he's a 'nut' because (a) he thinks the War on Drugs is destructive to liberty, (b) he thinks the US is far too entangled in foreign engagements, and (c) doesn't buy into the propaganda of the Magic Money Man we know and love as the Federal Reserve.
Funny thing is that I pretty much agree w/ him on all these issues, and I'm not a nut.
Ron Paul’s ideas actually support the Natural Individual Freedoms as posited by our BoR and Constitution and he does not support this flailing and unsustainable US Empire resulting in a massive tyrannical Central Government. The fervor of some Freepers to support US military intervention in every damn piss hole in the world, paid for by the 100M American taxpayers is what amazes me. Paul’s ideas seem more relevant to turning this country around than any of the GOPe and clones of Romney/McCain/Rubio/Cantor/Bonehead/90% R Senate.....there is a jihad against RP on FR for what reason I don’t know.
I’m not a nut either, I’m not even a Paulite, but I agree with him on a lot.
