Our founders warned to be vigilant about protecting our liberty. Their advice, and Paul's concern about the direction we're heading in is WISE, not insane.
You may not believe in what you consider 'conspiracy theories', but maybe it's the word 'conspiracy' that throws people off. There is clearly corruption in government, cover-ups, and there are statists who are growing the government and not upholding the constitution. To deny that is to deny reality.
The people spoke out and sent them packing, which is what happens in a Representative Republic. It's to be expected that one congress is more or less hostile to the founder's intention, but in the end, everything is salvageable, therefore, no need to keep peeking over your shoulders for Black Helicopters.
Hating your government to the point of irrationality will put your mind in a position to rationalize even kookier things, like 911 was in inside job.
