I'm a little confused. Did you actually watch or listen to the video? I'm thinking you did not. This video is against all you have mentioned.
Your QUOTE: "Is the Daily Paul now a terrorist website, or just a website used to paint Libertarians as terrorists who want to 'launch attacks on buildings and infrastructure along with conducting targeted assassinations'?"
There are factions out there that don't nessasarily call themselves libertarions, (yet there may be some libertarians) who are leaning towards violence. The message here is against violence and why.
Just thought of something though. Perhaps the title or caption of the video should read "Bring the Government back to the constitution" instead of "Over Throw"
