New Orleans Mayor Mitch Landrieu recently decided to take down several city monuments honoring various Confederate leaders. Unsurprisingly, he faced significant pushback for this decision. This is a link to the speech he gave explaining why he did what he did.
It is one of the most powerful and unflinching speeches by a White southerner on the matter of race, the "lost cause", and southern identity that I've ever read. It's not long, and I'm not going to excerpt. Just read it in full.
