I said this before in another thread and I think it is still applicable for this thread. BTW, I am NOT white and a LEGAL immigrant so "racist/bias/discrimination/ect" labels won't work.
===============================================================
Allow me to jump in (speaking from a point of view of a LEGAL non white immigrant myself).
ILLEGAL immigration is serious because we, as a nation, can't afford to let million and million of illiterate and unskill people to sneak in. We don't have open frontier/land/wide open space as we used to have in the 1800s. Resources such as water, land, comodities are finite and getting less and less available. Also, more and more available jobs (good paying) are demanding people with highly skills and education. We don't have (that much) the back breaking manual labor works that don't require education/skills anymore.
Another thing about ILLEGALS is that they ignore laws and regulations AND get reward for that. We have million and millions of well to do, well educated, highly skill people from other countries, and foreign students that were educated in the US, that want to get here LEGALLY yet they have to suffer years and years of waiting and huge cost to get here LEGALLY (if they are lucky). Why even bother to have immigration laws if a person can sneak in here ILLEGALLY and get ahead in front of million and million of others? No, ammnesty won't work because we tried that before several times and we are having bigger ILLEGAL immigration problems now.
Another thing, we as a nation (most of us), want the best for our country, therefore, we should get the best individuals for our "team". Let say you want to set up a sport team, would you pick the best players/highly skill for your team or the sorry players with "heart break" stories? Someone told me a while back, if we have to (in theory), we can make doctors, engineers, lawyers, etc. to mow yards, clean up toilet, nanny our kids but there is no way we can make illiterate people to do tasks of doctors/lawyers/engineers/highly skill and well educate people.
One last thing, LEGAL immigrants bring innovation, skills, ideas, creativity, brain power, and be highly beneficial to our nation. For example: Andy Groove of Intel, Google founders, Yahoo co-founders, and much more. See here (note the different racial/background make up)=

Would you rather let those people in and help us built a better US in a more competitive world or those illiterate ILLEGALS? The choice is clear.
