What is the separate-but-equal doctrine, and why do you think it was it accepted for so long?

Separate but Equal Doctrine is a doctrine designed to create equality between the races but never lived up to its expectations. It was accepted for so long because some legislators believe, such as Chief Justice Earl Warren, that Separation but Equal can never produce equality.

Separate-but-equal was a legal doctrine in United States constitutional law according to which racial segregation did not violate the Fourteenth Amendment to the United States Constitution, adopted in 1868, which guaranteed equal protection under the law to all citizens. It was accepted for so long due to racial biases inherited from the slave trade, and generational segregation practices.
