For starters, Woods says miscegination laws were put in place to protect blacks from whites, not to prevent the "pollution" of white blood by blacks. That is simply silly. He is apparently clueless as to when the first miscegination laws were even passed (try 1660s) and the CLEAR purpose was to prevent intermarriage so as to prevent the "inferior" race from bringing down the "superior" race. These laws were only passed when there were large numbers of interracial marriages showing up---clearly nothing to be worried about if whites were taking black wives, because black wives would be no more "abused" than white wives. But that wasn't what they were worried about: the Virginians were clearly obsessed by "black blood" mixing with white.
Do you recall the page number that is on?
