I'm not a child psychologist or mental health professional, so I'm not sure what to tell you, except that it seems reasonable to me to think that just maybe exposing kids to certain types of materials before they have the experience, emotional maturity, etc, to process those things can be incredibly damaging. And I really doubt that trying to avoid my 3 year old daughter watching violent pornography is going to harm her, but yeah, I don't have the data. Sometimes you just have to take a leap of faith.
