Sure all their 'evidence' is anecdotal (like the litter in your analogy) but damn if their premises don't fit the governmnet's actions the past few years. From Patriot Act, to NDAA, to TARP, to SB1070, to ObamaCare the government rules us and our lives with an iron fist.
What about those “tinfoilers” who have been crying out that there’s a major push for One World Governance, or that the true purpose of the Government is power: the power to control everyone’s lives?
Umm.. news flash. A lot of that intent is out in the open. You don’t have to be a tinfoiler to believe that.
Those of us who decry the tinfoilers are people who generally believe Occam’s razor and don’t need elaborate explanations involving secret conspiracies, when the simple explanation, that politicians want power and many people actually believe that socialism/statism is good and should be imposed, acceptably explains the observed facts.
