What constitutes the sphere of acceptable discourse in your class? Is it anything goes, or do you draw the line somewhere (e.g. use of slurs)? What effects do you maximize for when choosing a decorum policy (totally free exchange of ideas, your students feeling comfortable enough to learn, or something else)? Is it even possible to make all groups of students feel comfortable simultaneously, or is this an optimization problem?
I apologize if this question is too open-ended, but I couldn’t find much else like it on here.
