On Juneteenth remember that human trafficking was legal. Slavery was legal. Jim Crow was legal. US Govt paying reparations to white enslavers who lost their “property” but not to the enslaved who lost their lives, was legal.
Do not let legality be a measure of morality or justice.
And if you need another example, consider that prison slavery still IS legal and the private prison industry is a multi billion dollar industry on the backs of imprisoned enslaved people.
