Common ground requires a common set of facts. I try to share what isn’t commonly known which may indeed make many white people angry as I’ve experienced. Most of them don’t dispute the facts. They question why I want to bring up something that will only disturb people. My answer is so that we can work with a common set of facts. There are white people trying to start a race war. Black people are woefully unprepared for such an event. Those are facts. Have a great day as well.
