For much of history, laws in many countries were designed to uphold systems of privilege for white men. Segregation, discrimination, and unequal treatment were institutionalized, limiting legal protections for non-white individuals and women.
I mean, the legal discrimination against people of color throughout history has been accompanied by extreme violence and oppression. It's a brutal legacy that cannot be overstated.
Slavery and human trafficking, lynching and extrajudicial killings, Jim Crow laws, police brutality, denial of voting rights, economic exploitation, forced relocation and genocide, invasive medical practices, cultural suppression, and educational disparities... when you whinge about "decades" of legal protections for marginalized identities, I just wonder why you think you're making anywhere close to a salient or meaningful contribution to discussions of justice.
