But they have no right to be. After all, the road goes where the road goes. If you travel southbound U.S. 1 long enough, you are not surprised to end up in Key West. If you stay on northbound Interstate 5 long enough, you are not surprised to end up in Canada.
And if you denigrate, demonize and dehumanize long enough, you ought not be surprised to end up in bloodshed.
That is arguably the signature lesson of human history, but somehow, the teaching never takes. Each succeeding generation always seems doomed — or perhaps the better word is determined — to re-learn the lesson for itself, each time paying the horrific price of doing so.
