> Be the change you wish to see. If you think Biden was lying here, don't defend him for it.

Me criticizing Biden on an internet forum for offering comforting falsehoods will do nothing. He's responding to a tendency in human nature or perhaps American culture that is far too big to be moved significantly by so small an act, or even thousands or millions of such acts. So I'm happy to continue discussing this in realistic terms rather than idealistic ones.
