If you have a source to cite, please do, but I'm sorry if I'm not going to accept "I read this article one time years ago in a Confederate magazine, and this is what I remember it saying. Promise!" as historical evidence.
What a person with an understanding of statistics and/or polling does is point out the flaws in the methodology, what was measured, how what was measured might not support the conclusions reached, etc. For polling, there are flaws with the question asked, who was asked it, how the pollsters adjusted the responses to reflect the actual population versus the population that answers a land line between 6 and 10pm on a weeknight, etc.
And then there are competing "claims" about what the flag represents. To be sure, many associate the flag with some vague idea of Southern Pride or heritage. Others, particularly blacks oppressed under Jim Crow laws that were being fought like heck when that flag was raised as a symbol of protest of efforts to end them, associate the flag with racism and a defense of white supremacy, because that interpretation is consistent with the documented history of the flag.
So there are competing claims, and the way to resolve the question, "What does the Rebel flag represent" is a poll or polls. But you don't want to pay attention to polls because it doesn't support your "claim" about what the flag represents to most of us.
Everything in your life is a reflection of a choice you have made. If you want a different result, don't blame someone else, or expect others to make a change, you should stop complaining and make a different choice. Remember, the circumstances of your birth don't determine the outcome of your life.
