Alt: A screenshot from the book “Simple Sabotage Field Manual” with the text: “It also can be conveyed directly: statements praising the effectiveness of simple sabotage can be contrieved which will be published by white radio, freedem stations, and the subversive press.”
Void of the rest of the context, I’m tempted to say that the connotation isn’t race related, but more in the same way one today would refer to blue/red forces, or maybe black/white operations. I’m not sure what sets “white radio” apart from “freedom stations”, though.
Hanoi Hannah was an example of white radio.
