Age-appropriate racial terms. I'm writing something for a first-grade-level audience, and I'm trying to write a short spiel about the Civil Rights Movement, and both because of the age-related comprehension issues and the white-guilt-confusion issues, I'm not sure how to phrase things.
→[More:] My gut instinct is to use "black people and white people," but I'm worried it sounds weirdly condescending. "African-Americans" seems overly formal and maybe not right for seven year olds? "Blacks and whites" seems confusing.
As is probably obvious, I don't spend much time around kids. Can someone who does help me out? What's considered standard/appropriate?
