It's one thing to oppose Colin Kaepernick's protest. That's bad and weird, but whatever. It's a little bit worse, however, to suggest that black people should be grateful we brought them here and that they aren't in Africa. There's no way to spin that in a way that isn't shockingly racist.
That is... not what she said.
"Black people lived a better life here than 'in the places that they came from'" is basically exactly what she said, and it's been a racist talking point used to justify present day racism against black people dating back all the way to the height of slavery. It's profoundly disappointing to me that she said it, and I think we'd all do well to be aware of the history of such arguments.
