Did you unironically link a wiki article? Here you go sport. https://www.amazon.com/Marxism-Thomas-Sowell-audiobook/dp/B0099AE5X0 That one was written in the 80's, so you and the wiki author may have a hard time fitting it into your "conspiracy theory" narrative. LMAO Hey, maybe wikipedia has an article that explains the origin of the term conspiracy theory for you.
