I remember this. I grew up in a small town outside Sheboygan. An area where it didn't affect us at all, but people still had strong opinions on it! Thankfully, my mom taught me to support the Natives. But I also remember that we knew not to say too much about it, even among other family members, for fear of their reaction. My mom was a single mom which was a precarious position for a woman in rural WI in the 1980s.
Thank you for writing about this. It should not be allowed to be forgotten!
