I think a good start would be to talk to each other. For example, if you were a liberal, and I was a conservative--we would disagree on many points. But instead of insulting each other, what if we sat down and you told me why you believe certain things, and I could in turn tell you why I felt certain ways about things. Now all we hear are insults to both sides, and no one is listening.
Seakay, Rodney King was not beaten during a civil right movement. He was beaten during an arrest in Los Angeles, California. He was pulled over for a minor traffic infraction. He was combative but the cops went over the top and got carried away. I remember the incident very well.....oh I am feeling old.
