Something that few white people understand is the effectiveness of silencing Black voices with the implied threat of violence (whether physical or emotional) in situations of social discord. Many white people see Black silence as agreement or consent, when it's in fact an attempt at maintaining personal safety.
See, I'm not gonna say shit about anything. Why? Because I fucking know what'll happen to me if I say fucking anything. And I don't have it within me right now to have that nightmare happen.
White people, as a whole, need to seriously consider their place in that kind of a system.
