Jefferson and Lincoln were white supremacists

Leftists sometimes argue that the USA has long history of white supremacism, and it is amusing to note that this 2006 article by a pro-white group says essentially the same thing:

For today’s Americans it is an embarrassment to discover that their heroes were “bigots.” Historians usually ignore this or gloss over it. Most Americans have no idea Jefferson and Lincoln were “white supremacists,” perhaps because there have been deliberate attempts to conceal their views. For example, the Jefferson Memorial falsifies the third president’s views of blacks. Inscribed on the marble interior are the words: “Nothing is more certainly written in the book of fate than that these people [the Negroes] shall be free.” When Jefferson wrote these words, he did not end them with a period, but with a semicolon, after which he wrote: “nor is it less certain that the two races, equally free, cannot live under the same government.” ...

What of twentieth century presidents? Theodore Roosevelt thought blacks were “a perfectly stupid race,’ and blamed Southerners for bringing them to America. ...

Woodrow Wilson was a confirmed segregationist and as president of Princeton prevented blacks from enrolling. ...

Harry Truman is remembered for having integrated the armed services by executive order. Yet, in his private correspondence he was as much a separatist as Jefferson: “I am strongly of the opinion Negroes ought to be in Africa, yellow men in Asia and white men in Europe and America.” In a letter to his daughter he described waiters at the White House as “an army of coons.”
