However, since the 20th century, indigenous peoples in the Americas have been more vocal about the ways they wish to be referred to, pressing for the elimination of terms widely considered to be obsolete, inaccurate, or racist. During the latter half of the 20th century and the rise of the Indian rights movement, the United States government responded by proposing the use of the term "Native American," to recognize the primacy of indigenous peoples' tenure in the nation, but this term was not fully accepted. Other naming conventions have been proposed and used, but none are accepted by all indigenous groups.

Ah, so.. United States government

Human sacrifice in ancient Rome was rare but documented. After the Roman defeat at Cannae two Gauls and two Greeks were buried under the Forum Boarium, in a stone chamber "which had on a previous occasion [228 BC] also been polluted by human victims, a practice most repulsive to Roman feelings". Livy avoids the word "sacrifice" in connection with this bloodless human life-offering; Plutarch does not. The rite was apparently repeated in 113 BC, preparatory to an invasion of Gaul. Its religious dimensions and purpose remain uncertain.
