It's hard playing moral arbiter. On the one hand, you want to make it accessible to as many students as possible as well as teach them the core of what you want. You could probably replace much of the cursing without changing the underlying narrative.

But I also totally understand your point. Why is every marvel movie jam packed with gratuitous violence. To the point where fighting is the entire point of the narrative. Characters will die in fantastic ways but is still equally traumatizing. But portraying love or swearing is too adult for children. Makes no sense to me.
