Seceding from the union was not treason, no matter what northerners try to tell you. They had every right to do do, and states still do. And what makes you think they did so violently? You'd better have a better reason than fort Sumpter. The Confederate flag is used by many white supremacy groups. Guess what? They also use the American flag. In fact, they have done parades where the only flag they have flown is the American flag. Why haven't you condemned that flag as well? Statues are not to disrespect the federal government, they are to honor those brave men who fought and died for what they believed in. Have you heard about the black member of a legislative body, I don't remember if it was state or national, who was very sick but left his house to give his full support for erecting a monument honoring the Confederate dead. He himself had fought for them.
I am a patriot, and I would proudly wave the Confederate flag. The flag is not racist, nor does it symbolize that. It only symbolizes that to those who want it to, like yourself.
