It's handed down from generation to generation. But hate is not genetic. It can end.
People can choose to end the hate.
This is the lesson that ought to be drawn from the Winrod clan, who have occupied the front pages recently with their sad story of paranoia and racism. Gordon Winrod's father was a fascist sympathizer and bigot in the first half of the 20th century. He handed down the hate to his son, who has spent most of the second half of the century handing down the hate to succeeding generations, in hopes that they would spread it into the 21st century. The Winrods are an extreme, even sick, case. People of good will who have seen Winrod's newsletter are revulsed.
