Mississippi State Flag. Instead of the Confederate battle flag you can substitute another non-offensive Southern Heritage symbol - like the Bonnie Blue Flag. This flag takes original design elements, conserves Southern Heritage, and keeps it modern.
Southern Crescent is used. Nominally a symbol of South Carolina, but it is also a general symbol of Southern Values. In this case its meaning can be doubly extended to reflect the new communities of the Islamic South, which in 2015 is an extreme minority. Also note that an unknown, yet sizable portion of slaves brought over from Africa had Islamic heritage. The most famous being Kunta Kinte who was popularized in the Roots television series from 1977, played by LeVar Burton and John Amos.
Naval Jack of the Confederacy conserves heritage. It only has seven stars as Mississippi was a part of the Original Southern Seven. The seven states that left the Union before Lincoln was inaugurated include: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas.
Also note the Starry Symbolic preserves some of the modern design, but diminishes Southern Heritage Symbols, if not for basic framework of the original flag.
In the end it is a good bet that the Original Mississippi State flag from 1861 will be chosen. If the people of Mississippi decide to change their flag it will mostly likely happen on November 6, 2015. Reason being, it was 150 years from that date that the last in military service and official Confederate Flag was lowered on the CSS Shenandoah, on November 6, 1865, thus putting a final surrender and salute to the legion of heroes who severed in the US Civil War.
