my grandfather is related to Coronado one of the first spanish explorers of north america and he has married two non hispanic white women in his lifetime. He has three biological children and they all appear white. His grandchildren, all 5 of them, appear white. Yet these five young people are also hispanic and counted as such. My anecdote is an example of how the white population in America will remain stable (or grow) yet at the same time it will have a more pronounced spanish flavor, pardon the pun. Not to worry white people out there, America will remain majority "white" for a very long time thanks to all those migrants from mexico, etc....(my grandfather is also an immigrant from mexico, or his parents were anyway).
For those of you that think my story is in the minority, pardon the pun, a full 20% of all hispanic births every year in America are actually the cross between a hispanic parent and a non-hispanic white parent. The vast majority of these babies appear white yet are counted as hispanic. Again, EVERY single year. There are about 900,000 hispanics born in America every year. Roughly 180,000 (20%) of those are really non-hispanic white counted as hispanic. The other 720,000 hispanic babies are of unknown appearance but if its true that 52% of U.S. born hispanics marry non-hispanics (i.e. whites), then a majority of hispanics being white at the same time is not only possible but likely...hence, how America in 2050 or 2060, etc will still claim a strong white majority (70%+). The only change is that a lot of those whites will have spanish surnames or be the offspring of "mixed" unions with non-hispanic whites.
A white is a white, folks. If all these whites came straight outta Spain, would anyone care? or England, or anywhere else in europe for that matter? Again, a white is a white no matter where it comes from. Welcome to a new but same America, one with a strong white majority.
