Chris Rock tweeted on July 4 "Happy white peoples independence day, the slaves weren't free, but I'm sure they enjoyed fireworks."
This comment raised some eyebrows, including Herman Cain, who stated the following on CNN:
Look at it this way, if America had not become independent, slaves might still be slaves.
Actually no. They would likely have been emancipated several years earlier since the abolitionist movement in England blossomed into law with the Slavery Abolition Act of 1833 outlawing the practice throughout most of the British Empire. Yup, our former overlords freed their slaves a generation before we did, without a civil war.
