Which public statues should be removed, if any, and why?

Statues of “problematic” historical figures are coming down across the country (and the world, based on the news from England). We’ve had this discussion before, but I think it’s time to talk about it again. Do you support the removal of statues of historical figures? If so, which ones, and for what reason? Would you replace them with statues of anyone else?

I’m not a big fan of statues of people anyhow. They are rare where I am from and I cannot off-hand think of an example of one (a few statues near where I live come to mind and they’re all abstract or pop art). But they are more contentious in the South where many statues of Confederate generals and leaders exist in public squares, which some see as celebrating a legacy of slavery and racism.

Is the removal of statues asinine or an important symbolic move?
