America is a very different place now than in 1946.
I googled "most popular people in America" and Google shows me pictures and out of the top ten, half are African-American including Barack Obama, Michael Jackson, Muhammad Ali, MLK Jr, and Oprah Winfrey.
I looked at one page that had top ten most popular people in America in the 1940s and there were no African-Americans on the list.
> Your ancestors dragged these black people from their homes by force
Many slavers were African, particularly the ones dragging people out of their homes, and in 1946 very few Americans would have had ancestors who were either slave traders or slave owners.
