Well said. I think storytelling is an amazing medium precisely because it allows you to explore troubling topics in a safe way, with the linguistic layer of abstraction as a safety net. I check in with my players at session 0 and on occasion to know what is totally OK, what I can describe but not show art for, and what is off limits. We've agreed that sexual assault is off limits, sexual themes can be vaguely alluded to buy should remain mostly implied, spiders can be described but not shown, and everything else is currently on the table. This system should work fine for any table composed of reasonable humans.
