There were Indians Slaves in Texas before there were African American Slaves.
Indians were made slaves in Mexico, and Mexicans of Indian blood are still treated like dirt by upper class/ wealthy Mexicans.
Then you will not be as ignorant as believe only Africans were made slaves in the New World.
There were English and Irish Slaves also.
Course reality is not as soothing to some self-righteousness folks as bigoted ignorance!
The Ole Dog!
