They tried that at our highschool , they did it once. Cause we told our school board, if they do it again no taxes from any of us American Gringos. Stick together we pay the taxes they don't pay taxes, like the American taxpayer does.The school board said they would sell our houses, we said are you goin to sell all of them. The school board backed down. Too many emails and phone calls where we gave our names and keep the server and phones ringing. There is strength in being an American.New people who think our way in congress will not hurt either.
I think the demonstrations, with the pictures of Mexican flags, burnings of American flags, etc., have done a great deal to HARM the position of "illegal aliens". People I know, who have never really formed an opinion on the border issue (dumbbells!), have finally embraced the outrage! They've finally gotten the big picture.
One lady even fired her longtime gardeners when they couldn't produce green cards. She, finally, saw herself as part of the problem---one of those illegal employers.
