PHJim, I wasn't making that reasoning up. As I say, it was bandied about in the US 40 years ago by self-styled Black revolutionaries who were frequently in the news. The Black Panthers were the most visible and vocal of these groups. (Their most eloquent leader, convicted rapist Eldridge Cleaver, later became a Mormon and a conservative Republican businessman.)

Fortunately, almost nobody bought the argument that it's impossible for a black person to be a "racist." But it was indeed being made and apparently still is.
