I see it as something that is just barely better than somebody waving around the Nazi swastika and rationalizing it good because the Nazi were efficient and made the trains run on time. Some might say it's a representation of heritage or culture, but no matter what anybody says, no matter how it's spun, no matter how anybody rationalizes it THE SOUTH'S HERITAGE IS HATE AND SLAVERY. Why the hell would anybody want to take pride in that. You can't separate them. They are will forever be linked together. I'd say there is something wrong with people that willing take pride in the worst aspects this country has ever had. There is just no way the flag can mean anything more than it means about the South’s worst aspects unless one is completely ignorant or willingly blinds themselves to history and reality.
As far as the Federal Government gaining more power because of the Civil War. The system that operated under it didn't work, and there is no way it could work in the modern world. The fact we became one true nation after it was one of the biggest reasons we because as successful and influential as we did. People don't like it but things are so big, important, and complicated now there is no way to have anything function for the betterment of everybody without a strong central government. Even with that often we are barely holding things together. Some people don't like that. In some ways I don't like it, but it's true. We don't live in a agrarian 18th century world anymore where we buy almost everything from the guy that lives just down the street. In any case I'm not ever going to shed a tear because the side that condoned and exploited the most evil things we have ever did for their own selfish benefit lost.
