What did the Pittsburgh times refer to New Mexico citizen as?

As "a mongrel population too ignorant and lazy to assume the privilege of full citizenship."

Explanation:

New Mexico was initially a Spanish colony, over the years its population grew composed mainly of Mestizos, and American Indians who were the original inhabitants of the territory. Later it became part of Mexico.

In 1846 it was invaded by the United States, and later, in 1848, it was acquired by the United States, along with Arizona, as part of the Treaty of Guadalupe Hidalgo, and bought for 15 million dollars.

However, it was given a status of the territory, and not state, due to disagreement about declaring it a slave state or a free state, and also considering it as a Spanish colony with a very large Spanish-speaking population.

Despite this opposition, in 1912 it was officially declared the 47th state of the American Union.
