That's why I referenced Edmund Burke's speech without some history book filter. He spelled out exactly how the colonists were doing what they could to prevent a superpower from landing slave ships on these shores. Historian George Bancroft also wrote about some of the prevention efforts in his history books, particularly his best known 1854 work History of the United States, from the Discovery of the American Continent.
Again a speech, but Abraham Lincoln also defended the Founders against charges made by the slave owners of the south (this argument really isn't all that new) and this false distortion of history. To keep this short, if you are curious what Lincoln said it is here: http://tinyurl.com/n3aazgz
