The issue isn't so much that people are trying to "rewrite" history as they are trying to remove the honored status of the Confederacy. I'm a Texan, my family's been here since before the revolution and I'm proud of that, but I know entirely too many people who glorify what was, at its core, an act of treason against an elected government in the interest of preserving slavery. I'm fine with Confederate paraphernalia in museums, with proper context, so we can teach that history but it shouldn't be glorified or honored in public. That's what removing statues, etc is about.
