Piers Morgan fabricates stories about British soldiers abusing civilians. He is fired from his job because of it. He comes to the US as a guest. He trashes our societyand tells us to abandon the Constitution we have lived by for 200+ years and adopt the type HE wants. He gets incensed when he gets criticized for it and proceeds to lecture us on his civlil rights that he proposes denying to others. . Then threatens to leave the US.
What's stopping him from leaving? Its not like we would object.
