What should be done about Gettysburg?

On the anniversary of Pickett’s Charge, the Union spectators sit atop Cemetery Hill and the Confederate “spectators” emerge from the woods on Seminary Ridge and walk the nearly one mile to the Union “lines.”

Just as it appears that the Confederates will charge, they face each other at the wall, the commanding officers shake hands, and a pithy little speech about unity is given and everyone goes about their business.

Question: Should the shaking of hands be done away with? We wouldn’t shake hands with Nazis, right? Shouldn’t the Union commander yell at the Confederate commander and insult him and tell him he has no place in modern society?
