This is going to sound harsh. But you really don’t have much understanding of American history either race. My still living parents grew up in the segregationist south. This isn’t ancient history.
I believe you, and that doesn't change my stance. The segregationist South doesn't represent this country. It represented the remains of a racist Confederacy that was destroyed, save for the ideology that persists in the hearts of those that choose to continue to deny what this country has always been about.
Do we include you in support of that ideology? I worry that you might be missing the irony of your argument.
