Again, this is just not true. I have no problem making a judgement about a person who led a traitorous and secessionist army to war against the US for the sole purpose of preserving and expanding slavery. That was wrong, it killed more Americans than the Nazis, Viet Cong, ISIS, Al Quaeda, and the Taliban combined. We do not need to celebrate that mistake, and celebration is what glorious statues in public parks does. No one is saying we can't teach about him, or talk about him, or have museum displays about him, what we are saying is that him, and all other traitors should not be celebrated. We should decry them, what they did was inexcusable.

In addition, these statues were all installed during segregation, as a direct symbol to black communities of white supremacy. What you are saying is essentially moral reletavism, that you'd be fine with a statue to Timothy McVeigh. We as a society can decide that some acts and some figures do not deserve to be celebrated.
