PoC have a voice. If they have a fear, they can express it. They don't need a random white person hand-wringing on their behalf when that person self-admittedly doesn't even know how they might feel on the subject.
I never said white people couldn't "give a shit". I said that you self-admittedly don't even know the viewpoints of PoCs on ring doorbells. "Is slavery morally wrong" is a fairly easier question to answer in my book than "are cheap cameras available to most people morally wrong"
