There are several threads on the Confederate flag that dance around this question.
Many people, usually, if not always, conservatives, argue in favor of the Confederate flag and the desire to fly it or place it within the public domain. Oftentimes, they refer to it as if it is merely an innocent symbol of United States history, a symbol of state's rights, a symbol of fighting against far reaching federal government and sometimes even a symbol of patriotism.
However, these arguments, to me, seem like revisionist nonsense. The Confederate flag represents treason. It was the flag of people whose actions were not based in love of their country, but in a decision to give up on their country and abandon it in order to form a new one. It was a flag flown by those who decided that they no longer wished to be a part of the United States and that they no longer wished to solve their problems while remaining Americans.
Consequently, it seems obvious to me that the Confederate flag is not one that would be flown proudly by Americans, but one that would be flown proudly by those who no longer wish to be Americans. For this reason, it seems ridiculous to allow such a flag to be present on anything belonging to or issued by the state as it represents those who want to disassociate themselves from the state. It also seems ridiculous for anyone who considers themselves a patriot to fly the flag of people who abandoned their patriotism. Am I right about all of this? If not, why not?
