"Age gating" of History has gone on longer than The Internet. My middle school US history class ca. 1975 totally ignored the reality of antebellum chattel slavery. I didn't hear about the sexual abuse side of it until maybe 2005. I don't think that's in the middle/high school curriculum today.

Well reasoned! A car accident is something that just happened. It's not manufactured gore, but a fresh part of history, so take the sheets off the dismembered bodies and let my five-year-old see everything!
