Probably because of it's bold colors the Confederacy's battle flag has come to symbolize the flag of the CSA. That symbol has been so co-opted by radical groups throughout the world that it no longer represents the honorable history and heritage of our southern states.
The "Bonnie Blue Flag That Bears A Single Star" represented by our shirt shown here was in fact the CSA's unofficial flag of the Confederate States Of America .
The song "Bonnie Blue Flag" written and popularized during the Civil War and this flag has been pretty much forgotten by history but
can now be worn in remembrance of our southern heritage. Hurrah!
