I was born and for a time lived in the most segregated city in the U.S., Chicago. Dixie up north. Preach on concerning the righteousness of the Yanks. The North was signing the Irish & Scots up as they stepped off the boats. The North was victorious due in large part because of the Irish and Scots!
When I was transferred to NC., I became aware of the South's history & contribution to our American Revolution and the sadness of the War between the States. Brother against brother, family against family. For what? Nothing has changed, in fact, I believe things have gotten worse. I have no "white guilt," my parents taught me to judge people on their actions.
History cannot be changed, it happened. And Chicago's still the most segregated American city.
