Again, therein lies your problem. You and others do not read or learn anything about black people, black history, black events, etc. With today's technology, y'all don't even bother to Google these topics to learn more about them. There is no message in a book bout Rosa Parks. Pick up a book or Google Rosa Parks and you will learn about a black woman in 1955 on her way home from work, got on the bus. A white man got on the bus. The bus was full and the bus driver asked Rosa Parks, even though sitting in the "colored" section, to get up and give her seat to the white man. She refused and was arrested by the police. There is no message there.
Here is your homework. Google "Katherine Johnson mathematician at NASA". Read and learn about her life, particularly what she did at NASA, and come back here and tell us what you learned. By the way, there were a dozen or so other black women working at that time at NASA during the Gemini and Apollo programs who programmed the computers.
