That flag was actually the "Battle flag of the Army of Northern Virginia"

On a side note, the concepts that make up this flag and other confederate flags were borrowed from existing flags and designs, primarily St Andrews cross. Also, designs to various confederate flags were accepted and submitted from all over the country...including the Union & northern states, thats right, Yankees helped design confederate flags.

This flag was NOT one of the 3 flags used as national flag of the Confederate States of America, just one of many battle flags used.

Although my ancestors fought and died for the Union I believe that all such historic emblems should be preserved and it bugs me to see any used by rednecks and retards in a negative fashion.
