Racism?
I think I see the problem. There was racism involved.
You see, relatively few of the people who came into the country illegally were not folks who fit under the category "persons of color".
This is perhaps due to racial bias on the part of the administration which let all those illegals swarm our borders and gain entry.
If they hadn't been so racist in their 'admissions' polices, then the list to be deported might have a different complexion.
When it comes to deporting the people who came here illegally, well, you work with what you have. It would not seem racist, on the face of it, had it not been biased going the other way.
