There was nothing inherently offensive about the swastika either. It was used for centuries before being usurped by the Nazis
There is nothing inherently offensive about the name Adolph. But you don't see it used much anymore
The Confederate Battle flag was a symbol of the Southern Rebellion until it was usurped by the KKK as a symbol of black oppression. To many blacks that flag symbolizes the men who came in the night and burned and lynched. During the Civil Rights movement, that flag was waived as a reminder of the protesters slave roots
It may have been a perfectly acceptable symbol at one time....but it no longer is
And that would be a fair analogy had the Confederacy been about ethnic cleansing and white supremacy like Hitler and the Germans. Before it was a symbol of Southern rebellion or black oppression, it was the battle symbol of the Confederate Army. Under it, over 100,000 Southern Americans died fighting a war for their independence.
Instead of black people being offended by the flag, they should view it as an important and historic part of their past, where their ancestors ultimately won their emancipation. It is not often noted, but 65,000-100,000 southern blacks participated in the Confederate army as soldiers or other service personnel such as cooks, musicians, guards, and scouts. John Parker, a former slave reported that the "Richmond Howitzers were regiment partially manned by black people. They fought at the 1st Battle of Bull Run where they operated the second battery. A black regiment also fought for the confederates during this battle."
Frederick Douglass reported, "There are at the present moment many Colored men in the Confederate Army doing duty not only as cooks, servants and laborers, but real soldiers, having muskets on their shoulders, and bullets in their pockets, ready to shoot down any loyal troops and do all that soldiers may do to destroy the Federal government and build up that of the rebels." James Washington was a black confederate non-commissioned officer. He was the 4th Sergeant in a rec Co. D 35th in the Texas Cavalry in the Confederate Army. Freeman blacks were used in the Louisiana Native Guards, know in French as the Corps dÂ’Afrique. On Nov. 23, 1861, the Louisiana Native guards fought along the Mississippi next to the white regiments. The Guards consisted of at least 33 black officers and 731 black enlisted men.
So while it was uncommon, less than 1.5% of the Confederate Army, there were some blacks who also fought and died under the Southern Cross. And while we are all familiar with the abhorrent racist symbolism the flag has been hijacked to represent, it has also been historically used as a symbol of pride... During World War II some U.S. military units with Southern nicknames, or made up largely of Southerners, made the flag their unofficial emblem. The USS Columbia flew a Confederate Navy Ensign as a battle flag throughout combat in the South Pacific in World War II. This was done in honor of Columbia, the ship's namesake and the capital city of South Carolina, the first state to secede from the Union. Some soldiers carried Confederate flags into battle. After the Battle of Okinawa a Confederate flag was raised over Shuri Castle by a Marine from the self-styled "Rebel Company" (Company A of the 1st Battalion, 5th Marines).
