So this morning me and my friends were talking about a certain teacher who was openly expressing his political views through posters and other things he had hung up around the room. my friend said that she thinks it's okay to openly express your views in school while me and my other two friends argued that these things should be kept private or to yourself in a school environment to prevent arguments, and other disputes because not everyone is going to be okay with them (i.e. openly saying that you don't support the lgbtq+ community can make someone in the classroom feel less safe to be themself or feel uncomfortable with them) on the other hand, my other friend was saying that showing your biases and what you support should be acceptable because you can have civil conversations and debate in a friendly manner to get the other perspective (like we were)
What do you guys think? Should students (esp teachers) be able to express their political views in a classroom environment?
