While I have to disagree with a lot of the details of your historical analysis, let’s just say that in broad terms I agree that being human, minority communities aren’t paragons of perfection and could do more to help themselves. Granted.
But I still maintain that that is ultimately neither here nor there. As an analogy, let’s say I get into a fight with someone; afterwards, I don’t think it’s helpful to refuse to take responsibility for my actions until they take responsibility for theirs. That’s chicken shit. It just perpetuates the conflict. I have no power over their choices, but I do have power over mine, and I can choose to be humble and admit my mistake, even if I feel like they owe me an apology, too. And if they don’t offer it, I still know I did the right thing and I can be proud of that choice.
Now that’s assuming a relatively symmetrical conflict. In black-white relations, it’s completely asymmetrical with black people bearing the overwhelming burden. But let’s not dwell on that. Going back to my analogy, white people can choose for themselves how they’re going to respond to what is clearly still an ongoing conflict with our fellow black citizens. We can’t make better choices for them, but we can make better choices for ourselves. We can choose to treat them with dignity and respect, we can choose to be helpful. Or we can choose not to and then point the finger at them. That’s chicken shit, and that’s not what I choose to do. You are, of course, free to do whatever you want, but as a proud, upstanding sort of person, I would think that you would want to choose what best reflects upon you and your sense of honor and goodness.
