Whiteness is an exclusionary concept used to create an ‘ingroup’ and ‘outgroup’. Hasan Piker gives a great breakdown of it here.

Historically, it comes from a justification of chattel slavery. Painting ‘whiteness’ as purity and superior and ‘blackness’ as inferior and subservient. Leeja Miller gives a great analysis about how this has influenced Eugenics in American history (which inspired the ideology of the Nazis) which is still practiced to this day in certain circumstances.

It’s long, but Knowing Better gives an extremely detailed history of neoslavery in American history. To understand why ‘whiteness’ is still so prevalent in America in modern day, it’s important to understand the history of systemic racism and how it persists to this day.
