If after more than 100 years following a Civil War about it and an Emancipation Proclamation to boot they still consider themselves 'slaves' then its their desire to be slaves.
slavery ended over 150 years ago, unless you count those alive today who are still slaves to their own ignorance and self loathing.
Not just that. It's one black man who has a massive multimedia presence that they helped build saying he wants to think for himself. That's what really has them worried. They know how easy it is to manipulate opinion if you have access to that kind of media influence, because the left does it constantly. Any random black guy saying what Kanye says wouldn't matter to them, but Kanye saying it is a threat to their monopoly on shaping opinions.
