The inability of negroes to assimilate into American culture cannot be explaind by a single cause. I know...I know...that is a shock to those here who believe it has something to do with the inferior genes of a species that is subhuman to Whites, and I hate to be the one to break the bad news, but we all have our burning crosses to bear.
As Alexis de Tocqueville so presciently foresaw, freeing the slaves would not result in rapid acceptance into the larger society as it had in antiquity. The difference between antiquity and modern slavery is that the ancient slaves were virtually indistinguishable in appearance and background and education from their masters.
While the freed slave of antiquity had to merely deal with the prejudice of the master who despised someone who had been his inferior, the black slave was further burdened with the prejudice of race, and the prejudice of color.
While some white people may have been enslaved in America to a small extent, they were not targeted for special prejudices like blacks were upon achieving their freedom. Not even close.
Being "freed" did not mean being free. Not at all. As FA_Q2 pointed out, white society continued to subjugate blacks long, long, long after the Civil War. Just as Alexis de Toqueville predicted would happen.
That's not to say blacks are entirely innocent for their plight. But in their anger, much of which is entirely understandable, they have chosen demogogues who take advantage of their anger for personal wealth, fame, and power.
Take a guy like Al Sharpton, for example. Look at his blatant exploitation of Tawana Brawley to launch himself into the national spotlight.
We can find many examples of black leadership that is downright ugly and counter-productive and we would be justified at being frustrated at the black community's constant self-destruction in its choice of leadership.
We also find black culture actually criticizes anyone who tries to get along and get ahead on their own merits. This is what I refer to as the "bucket of crabs" problem. We all know the story of an open bucket of crabs from which no crab escapes because as soon as one begins to climb out, the others pull it back in. From where I sit, the black community seems to behave the same way. And that is a real shame.
Even in the present day, Barack Obama had to kneel before Al Sharpton and kiss his ring to get the go-ahead to run for President. You can see Obama actually blushing in their post-blessing photo op.
However, the black community is not exclusive in this behavior. Just look at the modern GOP. We see a party destroying itself in a very public fashion. While screaming that fags are going to destroy marriage, they very nearly selected a serial adulterer, Newt Gingrich, as the recent GOP candidate for President! And we have a GOP governor who abandoned his post and ordered his staff to lie to the people of his state about his whereabouts so he could run to Argentina to screw his mistress. And when he was caught, he actually used the Bible to justify himself for not resigning. The GOP has rewarded him by elevating him to national office!
One has to ask oneself, "Is this REALLY the best they can do?"
One could post many links to many stories of blacks or Republicans self-destructing. At least the black community has an excuse for being so fricking dysfunctional. The GOP has none. It has had nothing but privilege. It is such a shame both communities parted ways in the 60s. They would have kept each other honest.
