Well, The Great Debate says, "A place for men to impact each other by debate and exchange of ideas. This is a group where no ideas are off limits," so that is where I am going.
I lived in Mississippi for my first 10 years, and then in Louisiana for the next 17 years, so I think I can safely describe myself as a Southerner.
Although my trying-to-be-fair son called this the Southern Heritage flag, it still is literally the battle flag of the Confederate States of America as they sought to leave the United States (the Civil War).
The reason that I cannot consider it an innocent "Southern Heritage flag" is that it was used by segregationists including the Ku Klux Klan and became a symbol of racial bigotry. A symbol is only worthy of being used if the meaning of it is clear.
Another example: The swastika began as "a sacred and auspicious symbol in Hinduism, Buddhism, and Jainism and dates back at least 11,000 years" (Wikipedia). But once it was used by the Nazis, then it no longer was an innocent religious symbol but became a symbol of religious and ethnic bigotry.
For that reason, I feel that since the Confederate flag has been connected to racial bigotry, it can no longer be a neutral "Southern Heritage flag."
(And by the way, do I still love the South? You better believe it!)
Yeah, the "good ole days" some people reminisce about were definitely "good" if you were a white man. For others, not so much.
I see no problem with using the flag in reenactment situations just like for the Nazi flag.
That said I wonder what people would think if people put an ISIS war banner in the corner of a state flag. I wonder if that would be acceptable. I don't think it would be accepted.
I don't understand the idea that it is "Southern Heritage Flag". I see it as part of symbols a group of traitors to the United States of America. It is part of the symbols of a group that refused to stop owning slaves. I just don't see pride in slave ownership as a good thing.
Understanding can be developed.
When my wife from Wisconsin moved with me to our home in the Deep South, she told me she wondered why in the world there was so much Confederate this and Confederate that (the war was over long ago, for goodness' sake!). I reminded her that the Confederacy had lost; it was a different setting for them than for the Union. (Just saying....)
