I have already answered your silly objection that I cannot prove that a specific instance is the result of illegal aliens. It is the rise of a half dozen or more diseases that we eradicated here that have magically returned.
Let's try an experiment. Let us stop nearly all immigration, illegal and legal for a decade and see what happens. Then if I can be proven wrong I will happily apologize. But if once defeated diseases return to "defeated" status then you can apologize to every American citizen.
