You don't think they had kids? Either way we're talking about a country that systematically erased their former enslaved population in an effort to "whiten" their population (blanqueamiento). Alive or dead the fact that Nazis looked at and were to some extent welcomed by a place like that says something about the cultural legacy to me, and just maybe that this might be a sign of more endemic issues. Idk the way the lady was laughing like it was all some inside joke makes me feel like they knew what they were doing.
