Yes, they would be just fine. “Southern hospitality” really is a thing here, and our cities are much more diverse than what one might think if you haven’t visited. On my street where I live in my very affordable single-family home, we have virtually every major ethnicity represented, and everything from blue collar workers to doctors and software engineers.
Texas is different politically than California, but it is just as good a place to live for anyone coming to the Melting Pot. And in the end, both states face many of the same problems, the major cities are very similar, and the rural areas are also very similar.
Disclaimer: I live in Texas, and have lived in many other less cowboyish states, as well as living several places internationally.
