that ol' house Negro, Uncle Clarence Thomas.
You apparently haven't the first idea of the historical antecedents, thus the applicability, of the metaphor you used.
Clarence Thomas is not a man who'd ever have been a house slave, or, as you put it, "house Negro." In the days of slavery, dark-skinned blacks worked in the fields while light-skinned blacks worked in the house, hence the terms "field Negroes" and "house Negroes." (I'm sure there may have been some exceptions, but that was the norm.) It got so bad, that not only did the slave owners, who were often responsible for the lighter shade of brown his slaves had, give lighter-skinned blacks more respect, but so did the dark-skinned blacks.
Did anyone ask you to engage in racial "chest beating?" You bahs-turds never miss the opportunity to look longingly in the historical mirror at the racial mess your ancestors made and use it to make yourselves feel superior.
However, the sarcastic meme, House Negro, is actually a neologism borrowed from a more offensive term used to describe those slaves who lived in the "master's" house and took good care of him and doing anything, including betraying their brethren, to maintain their status.
Thomas may not be a chattel slave but it is plain to see that he was owned mentally and spiritually by Scalia. Scalia's death didn't change that. Thomas still lives, figuratively, in his master's house doing everything he can to undermine his own people. Like the House Negro of slavery times, his comfort and well being is paramount. As long as he has a good life with his masters, he doesn't care about the struggles of his own kind. Nor does Thomas give a damn about poor White people.
