Demographics in a population is indeed an important issue. Any student of Texas history knows that immigration by Anglos into Texas between 1821 and 1836 was an important factor in bringing about the Texas Revolution. However, there were quite a few Tejanos who joined with the Anglos in their desire to bring down Santa Ana who was seen as a tyrant and enemy of the 1824 Mexican constitution. Today, Hispanics living in Texas (at least the ones who have been here for generations) generally see themselves as Texans. There is sort of a Tex-Mex culture here which northerners probably find a little hard to understand. Things like music, food and leisure activities cross racial lines, and it is not really an
us versus them situation. Hispanics occupy all walks of life, and are represented in every profession. It simply does not make any sense for any Texan to want to become part of Mexico,
especially Hispanics who know more about Mexico than the rest of us.
Having said all of that, there is clearly a danger in rampant immigration from the South because we are talking about new people who have not been part of the Texas heritage, the U.S. heritage, or even the Tex-Mex heritage, all of which could be overwhelmed by sheer numbers in the future.
