A friend who has spent an unbelievable amount of time researching this issue had been telling me for years it was real and happening. I didn't want to believe it for the longest time because I was raised to believe people in their essence are good, but once I started paying attention, it became difficult to ignore/deny. Then came the pedopizza affair and the missing pieces fell into place.
On a lighter note, I saw a guy walking around in a shirt that said "Satan is my master" and, although I am not Christian, I yelled out "Jesus loves you anyway!" He looked like he thought I was going to attack him, it was hilarious.
