Sorry, but are you talking about Leviticus or the article? I don't know that I really get what the author's saying, but I don't think I can ignore Scripture.
Since we can cheery pick Scripture, How bout John 10-1— Verily,verily, I say unto you, He that entereth not by the door into the sheepfold, but climeth up some other way, the same is a thief and a robber.
Doesn’t that describe Illegal Aliens?
