I note that the idea of Third-Worldism is not my view, it was already a concept by Tito & Nassar to unite Non-Aligned(or Third World) Countries during the cold war. Internal oppressed groups in privileged countries, to me, usually come from the third world.

Many within the Working Classes of those states would call them opportunists & at most points, a lower race. Thus causing oppression. To Third-Worldists, These are the force for which they can unite Third World Countries by having the oppressed classes(of third world origin) within First World Countries revolt. This was the Attitude of Venezuela when the "Bolivarian Revolution" started.
