Did you even read the articles you linked? Some of the "facts" you state are directly refuted in the article. For example you wrote:
3. Anthony Johnson's first slave, John Casor, and most of the others he ended up owning, were white.
But the article you linked says:
In 1653, John Casor, a black indentured servant
Anthony Johnson himself was an indentured servant, just like John Casor, the only difference was that Casor was determined to have a lifetime indenture rather than a limited time like Johnson. A huge number of early colonists were in the US as indentured servants, they just didn't have the capital to move across an ocean and set themselves up without indenturing themselves.
5. Jefferson could not free his slaves as under the laws of the time, he would have been hanged.
Citation needed. You are claiming manumission in Virginia was a capital crime? Sounds like massive bullshit. Reading the Wikipedia article on manumission it specifically mentions laws being passed in Virginia to explicitly allow manumission, exactly what timeframe are you claiming it was a capital crime? Virginia did pass a law requiring a person to get the permission of the government to free a slave in 1723, but that was repealed in 1782:
The new government of Virginia repealed these laws in 1782 and declared freedom for slaves who had fought for the Colonies in the American Revolutionary War. The 1782 laws also permitted masters to free their slaves on their own accord
Heck, he could have freed them even earlier than that, since the 1723 law required permission from the Governor and from 1779-1780 he was the Governor.
4. Thomas Jefferson, the most-oft cited slave-owning Founder, never bought nor sold a single slave. He inherited them from his in-laws
Not completely true, he first inherited 52 slaves from his father, in 1767. He didn't inherit slaves from his in-laws until 1773. Also, Jefferson did free some of his slaves in his lifetime, from this page
In 1794 and 1796, Jefferson manumitted by deed two of his male slaves; they had been trained and were qualified to hold employment.
I'm not even going to bother with the rest of your claims, are you just making this shit up or do you have an actual source for any of your assertions?
