Look at the definition of rightwing extremists:
* (U) 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. It may
include groups and individuals that are dedicated to a single issue, such as
opposition to abortion or immigration.
So many of us just stop at the "hate-oriented" adherents definition. Now, I find out that I am a right wing extremist because I believe that state and local authorities do a much better job of governing than the feds do. Although, state and local governments are not immune to the problems that riddle the federal government, at least the focus is local and lawmakers seem to have a greater accountability.
I will not be surprised at how DHS describes churchgoing people. Before we know it, we will be persecuted for worshiping the one true God.
