The SPLC’s report… more “purposed” opinion than history?

In Robert Moore’s article regarding the opinionated reporting of confederate history, he speaks of a center releasing information that knocks down the idea that the confederate flag or confederacy is part of anyone’s heritage. He speaks of this information being very one sided and being focus on only one part of history which he does signal to not being very compelling but he does say that there is heritage behind the confederates and their ”top-down ” approach on their particular history is very deceiving.
