“We’re speaking about Black people experiencing these greater levels of racialized stress, which means we’re watching ourselves being murdered by means of racism, we’re watching ourselves not get jobs due to racism,” Grant stated. “We’re watching ourselves not get housing and equal alternatives by means of racism.
