No one said this person is an illegal human being, as in his humanity is against the law. It’s your immigration status that’s against the law, if you entered this country illegally. Then you haven’t just committed a crime, like any else at large, avoiding the authorities. You are an “illegal alien.” That’s the term for it, and that’s not “inaccurate.”
By the way, if someone told a Congressional panel they were another sort of criminal, a thief or a murderer for instance, wouldn’t they be in jail?
Well said, you’re absolutely right.
