The author predicts that the public will be in overwhelming support for the end of Plessy.
Explanation:
Plessy v. Ferguson was a secretive measure introduced in the USA. This measure sought to establish separate public spaces for blacks and whites. Supporters of this measure claimed that spaces reserved for blacks would have the same quality as spaces reserved for whites, keeping them "together, but separate". However, this was never functional in practice and blacks were subjected to spaces with poor resources and quality, in addition to being subjected to strong racism.
This decision was chosen as one of the worst that happened in the country, being recognized as harmful even by white people, which justifies that the end of this measure has a strong public support.
