Why should you care? Is their cause your cause? My ancestors were Tories; moved from NY and founded New Brunswick during the War for Independence to get away from the crazy patriots. I don't feel a duty to defend the cause they stood for.
In the South, many of us were raised being taught our heritage and traditions. I was taught much at the knee of my Great-Grandfather. Her Grandfather faught for the Confederacy. 140 years is not a long time in the grand scheme of things. I am also a Historian. Truth matters to me!
