This "open borders type" - as you choose to slander those who seem to disagree with you - never even thought of race. I did note the close proximity of Mexico to the United States, the sheer numbers from that country, and the economic disparities that exist between the two countries.
Qutie frankly, when you misrepresent people's positions, you seem to be trying to PROVOKE something. This is not about using the "race card" - if anything, some folks have used a "race-baiting card" to try to deflect attention from the fact that most - if not all - of the ire is directed solely at Mexico. You'll forgive me if I wonder why.
The economic disparities between the USA and Mexico is thanks the the same Mexican oligarchy that is pushing this "guest worker" but only for Mexicans plan. To save their corrupt system that makes some extremely rich but keeps most of the population in desperate poverty.
Social injustice in Mexico is the real driving force behind this massive immigration from that country. Many of the day laborers are NOT finding steady employment, not many employers of illegals value them enough to provide them health care insurance benefits or pay them well enough they can afford their own policy. The Mexican government is writing comic books --- shamefully admitting that is the literacy level it has provided it's citizens --- to encourage them to leave.
