What are the "other truths" that must be confronted? How do these "truths" complicate the idea of a melting pot?

The other truth that must be confronted is that New Orleans  was known to be America's largest slave market. At this place, hundreds of thousands of souls were bought and sold. They were also shipped up the Mississippi River. Many of them were tortured, forced into hard labor and raped.  Thousands were lynched and freedom fighters were beaten. These truths complicate the idea of melting pot because the atrocities that were committed are a dent on the history of America, especially New Orleans despite the fact that New Orleans is a city of many nations, a melting pot.

Explanation:

The speaker, Mitch Landrieu, a mayor of New Orleans made the speech during the removal of Confederate monuments. He reiterated that the truth about the atrocities that were committed in New Orleans must be confronted.
