The great State of Texas is now a majority-minority state. That means that Caucasians are now a minority of the overall Texas population.
By and large, that's a non-factor. Latinos have a long and proud history of work, service, citizenship and integration into the fabric of Texas society. The vast majority have moved to Texas to become Americans and fit right in: hard work, familial devotion, sense of community, desiring legal citizenship. And to those who fit that bill, Texans are happy to say "welcome".
