I don't think that's quite true, either. Parent poster said it was amazing they were still sane. Other people might not be sane, depending on what they were exposed to at an early age. And watching something on video is different than seeing it happen in front of you, which is also different from having it happen to you ...and I understand the impulse to say that we're not a victim of anything just because we saw something horrible.

But lots of people seeing lots of horrible things, if it doesn't traumatize them, can desensitize them. There are plenty of freedoms that also cause harm. That doesn't mean the freedoms should be taken away, but it means that the "third party" is often correct. Society in a free country calls its own balls and strikes.

Some things should be hard to access. Accessing some things should also be taken as a red flag that you are not OK. The rest of the people around you have a right to their security as much as, or more than, you have a right to your freedom to view illicit information. And I say this as a person who would absolutely revolt against any system that based that decision on fiat, religion, or unfounded hysteria. We all personally have a right to do anything we want that doesn't hurt anyone else. But if the "third party" you're talking about are your neighbors, and if they have decided that you are a threat to them, then talk with them.
