@maxdancona,
I've heard about de las Casas for many decades but have never read the book.
In my early education, I wasn't taught, or perhaps didn't take what I was taught, that Columbus was somehow wonderful; more that he found the New World rather by mistake. I didn't hear/read about Ferdinand and Isabella and their scalding reign until I was older.
All in all, I'm glad these lands were found, would hoist an aperitivo to that, but not the treatment of the people, the decimation of the people already on the lands.
I take it the Italians in the US are into Columbus Day parades (or are they?) but I don't remember reading about Italians in Italy being so gung ho about him. Maybe I missed it.
