From the report, p.2: Rightwing extremism in the United States can be broadly divided into those groups, movements, and adherents that are primarily hate-oriented (based on hatred of particular religious, racial or ethnic groups), and those that are mainly antigovernment, rejecting federal authority in favor of state or local authority, or rejecting government authority entirely.
But.....the Constitution states clearly that the authority not specifically granted to the Federal Government is reserved to the States and the People.
I plead totally guilty of promising to Protect and Defend the Constitution and this Nation, and will continue to do so as long as I live.........
