Well,I disagree.I read the book about Richard Ramirez and that was shocking enough.And reading Scourage of the Swastika in Seventh Grade gave me plenty of insight into Nazi war crimes and concentration camps.
I did not need to see it all displayed in bloody Technicolor.
If you went to see the Passion of the Christ...you heard weeping and crying from people who have read the Bible a million times. They really didn't fully understand what our Lord went through until that day.
I don't want to look at these things either but I consider it my responsibility to understand to the best of my ability what is going on in my world and I never take anyones word for anything without analyzing the data for myself.
Same goes for racial relations. Go out into your community as you have done and see for yourself. It's the only way to be fully informed.
