Judah: I have issues with a couple things you said.

1)  you wrote...."I wasn't referring to "white supremacy," ....This is an ideology finally died in the 1960s."
Well you might want to tell that to Richard Spencer, Cantwell, and many other neo-nazis that are planning marches all over the USA because apparently they missed the missive from you that white supremacy is over. They white supremacist/neo-nazis have made these statues rallying points to attempt to win converts by putting their message in the light.

It seems to me you have an incomplete view of racism in the USA. I am not attempting to say that with malice you are just speaking of it academically and I am speaking about things from a real world perspective.

Removing statues of traitors is not airbrushing, nor does it create asymmetry. Those traitors can still be learned about in school and books. Glorification by building a statue is different than learning history about what actually happened.
