In an Instagram post last week, Black Lives Matter (BLM) cofounder Patrisse Cullors shared a National Public Radio (NPR) article about black homeownership levels, lamenting “white supremacy” in the housing market.

“Thank you @npr for highlighting the history of racism inside of the housing market and why Black homeownership has always been a way to disrupt white supremacy,” Cullors wrote.

Breitbart News reports that the NPR story was part of a documentary called We Hold These Truths, which investigated how blacks have been discriminated against by the real estate industry and government policy for decades. The report highlighted the experiences of black people residing in Compton, California, revealing 41.8 percent of black households own their own homes.

Experts say the reasons for low homeownership rates stem from low wages, historic unemployment, and a recession-related foreclosure crisis that hit the black community especially hard.

Here’s how white supremacist the housing market is: the Marxist revolutionary Cullors has purchased at least 4 homes since 2016, some in predominantly white neighborhoods of Los Angeles, amassing a real estate empire worth nearly $3 million.
