it is important to note that the incorporation of the Confederate battle flag into Southern state flags and flying it at capitol buildings isn’t some relic of the post-Civil War days. It’s quite new. In most cases it goes back a little over 50 years to the 1950s and early 1960s. In other words, the prominent public display of the flag (if not the popularity of the flag itself, though partly that too) doesn’t commemorate the Civil War or the Confederacy, it was the emblem of the ‘massive resistance’ movement of the 1950s and 1960s in which white Southern state government sought to defy the federal government’s effort to force desegration, black enfranchisement and formal legal and political equality for African-Americans on the South.
Worth a read. Confederate flag defenders are unintentionally hilarious.
