That has never been a reason for erecting a statue. Confederate memorials are unique among war memorials in this country.
Most were mass produced and erected well after the war, even in states that were not part of the confederacy or did not exist at the time of the war.
Other war memorials are aldo typically either in cemetaries or to commemorate battle ground sites. Not so the Confederate ones which were often large and prominantly displayed in town centers..
When ever there was a major racial upheavel (Jim Crowe, civil rights) there wasa sudden surge of new monuments, often in towns with a significant Black population.
Should Germany put up memorials to the Nazis? Should they be put in towns whith significant Jewish populations?
Just food for thought here but why not treat them like other war monuments....place them in cemetaries and historic sites?
I think that is a valid concern given the tendancy of people to go too far in either direction. BUT Washington did not participate in the Civil War did he? I don't agree with removing statues simply because the person had slaves, historical context matters and if the reason for the monument had nothing to do with slavery, why remove it?
I don't it is that blurred in the case enslaving peopme and fighting for that "right" or similarly, what the Nazi's did. There might compmex reasons for war, but that doesn't mitigate the fundamental evilbeing fought to preserve. Again, it is a bit like making a casethatGermanyshoyld etect statues honoring major Nazi commanders and figures.
