The conditions that apply to an "Ethics tutorial in a philosophy paper" aren't universally applicable, and that isn't a sign of something being wrong. It took me a while to understand this myself.
Suppose you wished to discuss "ethical problems" in a tutorial, people can do that, and in some other (limited) environments too. You might - to invoke a particularly awful idea - like to hypothetically explore whether what people wear had relationship to their likelihood of being targeted for sexual assault.
If you are in a position of leadership however, you incur responsibilities. People under your leadership must be confident that if someone were to tell you they have been sexually assaulted, your response would not be to wonder what they were wearing. The reason for this is, as is well established, that speculation over what women (or survivors in general) were wearing at the time they were sexually assaulted is a loaded idea that has widespread use in casting blame on the victim of sexual assault, and has been very effective at this for hundreds of years, leading to a vast amount of preventable suffering, all because of we continue to tolerate the mistaken idea that women might somehow 'invite' their own assault.
A person in a leadership or representational role doesn't get to publicly speculate about "clothing and sexual assault" in the abstract, because they have a duty to be aware of how incredibly damaging that is in the general sense, and how public speculation about that sort of relationship would clearly act to dampen survivors of sexual assault from coming forward, including in the org they are leading, in addition to being distressing for the people who have experienced it in the past, which is a significant fraction of people in general, even supposing the speculator meant well.
