Gay marriage is a better example in my opinion.Also, it took a literal civil war -- with people shooting cannons at each other and burning down cities -- to end slavery. Then a bunch of constitutional amendments that were enforced by a military occupation of the former confederacy. When that military occupation went away, the pro-slavery confederates transitioned directly into a system of racial terrorism and segregation that lasted until the 1960s. So basically the people who were in favor of racial apartheid in the US controlled significant chunks of the country from the 1600s until approximately the Johnson administration. Not sure I would have nominated "slavery" as an example of a transitory issue that vanished into the ether as a result of people realizing the error of their ways.
