seems unlikely

As of 1 July 2017, 83.3% of Arizonans identified as "white" and only 13.4% were foreign-born

While it is true that only about 55.5% of the population considers themselves non-Hispanic/non-Latino white, the first non-aboriginal settlers were (as the state name might suggest) Hispanic -- and they started showing up there after 1539, building a number of missions in the 1600s and 1700s. It didn't become US territory until after the Mexican war, and Arizona didn't become a state until 1912

The 2016 American Community Survey indicated that about 73% of all adults speak only English at home and about 71% of all school-age children speak only English at home

About 20% of Arizonans speak Spanish at home. The next-most-common language seems to be Navajo, spoken at-home by about 1.5% of the population

Better make nice with them...

Plenty of garden-variety racism involved, but the fact that U.S. whites are becoming the minority is key, especially when you consider they tend to vote Democratic.
