If loyalty is, and always has been, perceived as obsolete, why do we continue to praise it? Because loyalty is essential to the most basic things that make life livable. Without loyalty there can be no love. Without loyalty there can be no family. Without loyalty there can be no friendship. Without loyalty there can be no commitment to community or country. And without those things, there can be no society.
