The appropriate response is Dred Scott v. Sandford. This was a point of interest choice by the United States Supreme Court on US work law and established law. It held that "a negro, whose precursors were foreign made into [the U.S.], and sold as slaves", regardless of whether oppressed or free, couldn't be an American native and subsequently had no remaining to sue in elected court;and that the government had no energy to direct subjugation in the elected domains gained after the making of the United States.
