In their universe, anything Obama does and anything not explicitly sanctioned by the Tea Party is illegal.
There was at least one guy who sued against deployment to Afghanistan on the grounds that Obama is an invalid Command-in-Chief (Birther) and thus all military orders were null and void. Obviously went nowhere but I don't think it's a stretch to assume that there are Birthers in this group.
And of course no one thinks any of the illegal orders they are promising to disobey will even get issued unless you're a black helicopter nutcase.
sure, no rational person expects that the government will ever be involved in warrantless surveillance, detention without trial, seizure of private property without due process, or anything like that...
