This week in the culture war: The Waukesha School District in Waukesha, Wisconsin prohibited first-graders from singing Miley Cyrus and Dolly Parton’s 2017 collaboration “Rainbowland” on Monday, citing a rule against “controversial” issues in the classroom. Nodding to the LGBTQ+ community in its title, lyrically “Rainbowland” addresses inclusiveness in the most general terms, with lines like “Wouldn’t it be nice to live in paradise/ Where we’re free to be exactly who we are” and “Let’s all dig down deep inside/ Brush the judgment and fear aside.”
