 A condensed answer would be, I stopped teaching Kalkal-Beri-Fin and I'm a professor at a college and I have tenure and I do it, I stop teaching it because I think it's inconsiderate for me to teach it in certain circumstances. If I go back to teaching it say next year, there will be norms in the classroom, like I said, in terms of what's nothing said aloud, which I've had in my classroom.
