re: Spanish speaking in the United States

"The numbers are vastly different, and the population is coming from a neighbor rather than overseas, and that neighbor happens to have a historical claim to vast portions of US territory."

Mexico has a claim to vast portions of US land??? Mexico signed the Treaty of Guadalupe Hidalgo in 1848 in Mexico. Mexico has no claim of any kind on US territory nor do they claim to have a claim!

Any worry about too many Mexicans speaking Spanish is off-base, imo. BY the second generation, English will be spoken fluently by the overwhelming majority.
