While I think your article makes good points about the need to get rid of erosive sterotypes Americans and Mexicians hold against each other, your need to make Mexician immigrants "special" really pokes holes in your credibility.

All immigrants throughout American history have been subjected to harassment in some form or another, even if the labor industry welcomed them with open arms. Signs were posted in shops, "Irish Need Not Apply." Being Irish was not always fashionable. (This is lame, referencing wikipedia, but I just don't have the strength for peer-reviewed research right now: <link>.)

Racism against German immigrants was especially high, even before the explosion of WW1 and 2. Prohibition was a special blow against German-American communities; beer and town hall gatherings were part of their deeply ingrained culture.

And my gosh, do we even want to touch on Japanese immigrants, whom were placed in CAMPS during WW2? And these were legitimate, legal immigrants, citizens of the United States.

There has always been pressure to assimilate into the culture that one is joining. Perhaps some of the rancor against Mexician-American immigrants is the perceived (and sometimes published) threat that they're simply moving Mexico into America, instead of becoming assimilated American citizens. I grew up in a Wisconsin community, went to school with 2nd and 3rd generations where Norwegian was still used sparingly among grandparents, and being told in school we MUST learn Spanish (I was told specifically it was idiotic to take French) because we'll soon be speaking it anyway, when our grandparents worked hard to become Americans while still retaining their heritage, rubbed the scar a little raw.
