Quite possibly. I'm unsure about the value of these warnings at all really. I've heard people argue that the title of their stories give away the topic matter, so if that's a trigger, don't read it. I guess when it's part of the curriculum, it's respectful - maybe they can opt to read something different. But yes, there's then potential that 'content notes' become a trigger - and at some point, people have to learn to live with the fact that there are potential triggers all around us.
