I've see and heard Sowell on YouTube before.
But that's not what the question on this thread was about.
It was about the video shown in the OP.
Just so we're on the same page;
Definition of propaganda
1. capitalized : a congregation of the Roman
curia having jurisdiction over missionary territories and related institutions
2: the spreading of ideas, information, or
rumor for the purpose of helping or injuring an institution, a cause, or a person
3: ideas, facts, or allegations spread deliberately to further one's cause or to damage an opposing cause
Other than the first, what was said in the video that was nothing more than propaganda ?
