Yes, advocating such widespread changes to society on the basis of a specific interpretation/understanding of the constitution (the root document of our government) fits the meanings of the word almost too perfectly:
> Arising from or going to a root or source; basic.
>Departing markedly from the usual or customary; extreme or drastic.
> Relating to or advocating fundamental or revolutionary changes in current practices, conditions, or institutions.
> designed to remove the root of a disease or all diseased and potentially diseased tissue
> of or relating to the origin
> favoring extreme changes in existing views, habits, conditions, or institutions
> Favoring fundamental change, or change at the root cause of a matter.
