This explains so much.
Recently the local tv news station switched to a facebook commenting system. They were having a really bad problem with trolls. The trolls were so awful that after my daughter's wreck I wouldn't visit that news site anymore. (We don't have tv.)

Since they switched to the facebook system, I check out a story now and then (the newspaper does a better, more accurate, and more informative job of reporting though). Yesterday another cyclist was hit and so I wanted to see what the comments on that story were like, compared to the horrible things they posted about my daughter.

Because of the facebook system I can see the name and employer of the people who post. Of the 5 who posted before I did, 3 are high school students. Here's the story.

That explains so much.
