Civil Rights history. I can assume the low ratings are individuals who want to 'whitewash' this part of history. Same idea with the Holocaust, if people don't believe it happened - they will attempt to remove it's history. Rosa Parks pushed it is about education, learning and information don't be blind to items you disagree with. Don't tolerate politicians trying to ban books, discussions of LGBTQ or other sexuality topics. As people try to remove history, there is a greater chance it will happen again. Civil Rights was the push for equality. The entire message is everyone should be treated fairly regardless of race, gender or race.
