For your next public gathering, ball or reenactment event have a group like the Unreconstructed Band play for your event. Picture From 180 Degrees True South 33. Wear A Confederate Flag Shirt To School or Work - But be prepared to lose your job or be sent home from school.

Private property is a different matter.
Buy Confederate checks and order a stamp and envelopes that convey a Confederate symbol or message to both postal employees and the mail recipient. On a recent visit to Padania, the aspiring nation in northern Italy, I noticed pro-independence graffiti on every vacant house, wall and barn. It provided a very effective message - one that could be easily emulated here.
