Obviously something like this would never be created today, but its original intent was not to perpetuate stereotypes or glorify the "lost cause" like many of the statues being torn down recently. If there was a statue that should be kept as it is because it has true historical significance, but with an informational plaque in front of it addressing the stereotypes it depicts, this would be a great example.
Yeah essentially this. The optics aren't great, but it was meant to show Lincoln as a liberator, so I say keep it up.
