A Wisconsin school board voted last week to ban teachers from displaying Black Lives Matter and gay pride flags in their classrooms, saying such displays are political messaging.

With only one member opposing, the board of the Kettle Moraine School District in southeastern Wisconsin voted last week to affirm district Superintendent Stephen Plum’s decision to interpret the district’s ban on political messaging in classrooms to include prohibitions on the display of Black Lives Matter and gay pride flags. District staff are also barred from including their preferred pronouns in their email signatures.
