His whole theory that darkskin blacks are hypocritical because some of us want to be lightskin is ridiculous on its face and if asked to verify and source that claim, he wouldn't be able to do it.
The false mythology of lightskin being in the house is part of the willie lynch mythology, a known lie.
Fact is they had lightskin and darkskin slaves in the house and in the slave quarters. There was no better treatment based on where they worked, and to be honest it was more dangerous to be in the house, because closer proximity to whites in the house, meant easier access to be victimized.
On top of that, if you read a book called, The slave's war by Andrew Ward, you would see in slavary times, it was more common for slaves to claim and be proud of their darkskin. As a matter of documentation they found that the origin of blacks saying they were part native american, was actually to deny them having to admit they were b*stard children and the product of white rape by their master. They said they were part indian because most were ashamed to have to admit they were part white.
