I'm new here at Free Republic. Could someone please explain tin foil hats?
Tin foil hats are references to assorted crazy folk who in days gone by, used to cover their heads with tinfoil to prevent the influence of government (or extra-terretrial) mind control waves.
To suggest that a post is a tinfoil hat post, implies that it is a paranoid delusional conspiracy theory or a technically ridiculous bit of drivel unworthy of serious consideration.
