I used to have a few Dutch friends. It was jarring how cavalier they were about Black Pete and how in denial they were about the racism associated with the tradition. A very similar mindset to white Americans who think it’s okay to dress up like Pocohantas as a costume.
If geopolitics is actually their interest, I share John Mearscheimer’s lecture on Ukraine with them. It both helps that he isn’t a communist and that his analysis and breakdown is accurate and accessible.
