There are a lot of great, hardworking teachers out there. There are also a bunch of teachers who seem to see the classroom as a place to work out their own issues. Teachers are people, and a lot of people are racist. A woman named Trameka Brown-Berry shared a homework assignment her son, Jerome, brought home from school illustrating exactly that.
Brown-Berry posted a photo the assignment questions Jerome was asked to answer. For context, he's only in the fourth grade. The worksheet demands that he give three "good" reasons for slavery and three bad ones. Good is in quotes, I guess to indicate that they wouldn't really be good reasons? Which is a red flag the teacher should have paid attention to. If you already think your question is stupid enough to need qualifiers, don't ask it.
