This is an article from The Atlantic by Greg Lukianoff and Jonathan Heidt. First off I'm of two minds set on it. I agree that we need to mindful of trigger works or what not but at the same time not in collages! (If you don't want to read or totally disagree with me that is also fine.)

How can you be educated by not hearing new ideas, different sides of an argument or how the world works around you. Collage is where you are first met with a big change and a challenge that no everybody thinks alike.
