Playing "Who Are They", the GI Rights Network is a coalition of nonprofit, nongovernmental organizations. They are, variously counseling for military people with problems and pressure groups with distinct social partisan agendas. Per W'pedia, the affiliated groups include:
Humboldt Committee for Conscientious Objectors (Arcata, CA)
Military Law Task Force of the National Lawyers Guild
Bay Area GI Rights [BAGIR] (San Francisco, CA)
Center on Conscience & War (CCW)
Quaker House Of Fayetteville, NC
Flint Hills GI Rights Hotline (Manhattan, KS)
It's a partisan political outfit that deserves to have their Hate-Trump hotline spam-called to Valhalla.
