So you are calling Mr. Williams a nut? Are you a racist?
Not at all. Williams explains secession can be accomplished and how that can happen.
What he doesn't (explicitly) do is say it would be a good idea or recommend it.
The "nuts" are those who are spending a bunch of time and energy in thinking it can or will actually happen and/or advocating for it.
I'm rolling up my sleeves to get real work done. Not engaging in a bunch of counterproductive, sour grapes whining.
