I commented that based on the slurs of him from the black community. I do not know the full story but shared it based on what I hear from my black friends. It was explained to me that he was a bad dude that sold out other black people. Similar to Uncle Rukus in The Boondocks.
With that context, I meant it as there is the black uncle tom that sold out other black people and now we have American uncle tom selling out America.
