My father was a WWII GI, center-right on all the issues of the day. He was a Sam Nunn/Scoop Jackson Democrat, but he would never ever have voted GOP: to him it was the party of the Potters (as in It's a Wonderful Life), the rich Rockefellers, and most importantly, Tricky Dick, whom he hated with a passion from before the time I was born ('54). He thought of himself as poor even when he was middle-class professional, because he had grown up poor in OK in the Depression, and only the Democrats cared about the poor. Like many of his generation, he agreed with Reagan on everything, but he still couldn't make himself vote anything but straight-down-the-line Democrat, all the way until he died in '96.
That's exactly how non-thug, non-welfare blacks are. They think they know "black history" but they don't know squat, and there is no well-funded organization (there's the John Langston forum, but who's ever heard of them) to get past the progressive DuBoisian drivel that passes for "black history" in every community, black or white. They think only Democrats care about black people, and Barack Obama was their JFK--except that unlike JFK, who got martyred before his shine turned to rust, Obama is still rusting, and it is getting to the point that even the average non-thug non-welfare black is beginning to cringe at the Obama name.
It will take a generation of blacks not educated in what passes for public schools to break the spell, but it can be done, and as the public schools collapse, it will be done. I was born the day the Supreme Court handed down its ruling in Brown v. Board of Education; I hope I live long enough to see it, but if I don't, my children will. I have the same dream as someone else once did, and I'm a whitey.
I agree with you that things can change -- over time. For me, the proof that "change" has occured, definitively, for black Americans is when it's reflected in the vote. Otherwise, for all practical purposes, it doesn't matter how "conservative, patriotic and religious" they are. I.e., if they keep it to themselves, it's wasted. I would also argue that the socialists' agenda of overwhelming us with Mexicans and South Americans is going to make black Americans' political voice rendered moot in very short order.
