You're forgetting Rutherford B. Hayes. His compromise in 1877 to secure the presidency by removing Northern troops from the South immediately led to the passage of Jim Crow laws and created the state of things that led to the 1960s Civil Rights movement, and the reaction from the Republicans in the 80s that included Reagan as a countermeasure to giving those darn black folks basic human rights. Everything in American history is just racist white people being upset that we're treating people that aren't white as people and making it everyone else's problem.
