I have to say I completely disagree, it is the right of the state to secede, and I personally believe it must happen to fix the country (well, at least state-level nullification). The subsidies you discuss were stolen in the first place, so the federal government should pay back all income taxes, plus interest, collected since 1913 first.
Though signing petitions? You shouldn't be asking permission to secede, the colonies didn't ask King Georges permission.
