The video below—White Girls Black Dolls: Destroying White Bias —is an analysis of the semiotics of dolls.
A doll can be a powerful cultural sign—a semiotic—that can be manipulated to achieve various effects.
Since semiotics (and dolls) can be manipulated and are manipulated by people, semiotic analyses of this kind should say who is doing the manipulating and why.
This video claims that a great deal of the manipulation of white/black cultural semiotics is and has been done by Jews. This is a reasonable claim supported by evidence, some of which is presented in the video.
Senator Joe McCarthy is mentioned in this film. His reputation as a maniac who wantonly destroyed the careers of innocent people is false. His reputation has been manipulated in ways not dissimilar to how dolls are manipulated.
There really were communist spies in the US government. They really were doing harm. You can check this claim by looking into documents released from the Venona project and the Soviet archives. It is most likely that McCarthy was being fed true information by J. Edgar Hoover.
There are a couple of books that exonerate most of what McCarthy said and did (he did go too far sometimes), but even with all this evidence it will be a long time before the semiotics of his reputation change. Most people will see him as an archetype of badness for long time to come.
Obviously, this prevents us from understanding who those communist spies were and what they were doing, but that is another story. Semiotic manipulation can hide things as well as direct our attention toward things.
You cannot possibly understand cultural life today without having a rich appreciation for how and why the signs and symbols—the semiotics—of culture are consciously manipulated by people, people who often have bad motives or at least motives that are not in your best interest.
