its well documented that immigrants will learn English within the first generation, also it is well documented that 2/3 or more of recent immigrants in the south west are illegal, therefore then anyone using Spanish has a greater probability they are a newcomer and illegal at that,
simple statistics; the kids learning English are the kids of illegal immigrants by and large even though the kids themselfs may be US citizens but more so are the families of legal parents made up of both parents and children whom are legal citizens and whom the parents have paid taxes there whole adult life so now are being cheated , is what they are saying.
