As other have said, my experience with Facebook just doesn't mirror the "angryness" and hatred that other people are seeing. My Facebook stream is just every day things from friends I have made through the world. It is very useful for me to maintain a bit of a touch with people I esteem so much but with whom I've list touch through the years.

The "angry facebook" experience to me seems like the moms against heavy metal / twisted sister case: People are seeing a reflection of what their peers share.

If their circles are angry and share disinformation, that's what they will see.
