I guess I could say I found ogrish or liveleaks traumatizing but it wasn't the site, it was human beings. I felt I had a responsibility to understand what humanity was capable of, because I only had vanishingly-minor hints of it growing up in a nice conflict-free region of the world. Honestly, being exposed to the stuff on those sites gave me a better understanding of what people might do to each other (or to other life forms). It was rough to see some stuff, but I am actually thankful I was able to access that kind of stuff at that age and learn more about what humans are. I don't know if many people relate to that mindset, but I never once had a sense of "I wish I didn't watch that". Each was a learning experience.
