Not being civil to one another. We should learn to respect other people's opinions. I understand that, sometimes, we can get passionate over some subjects but that does not justify calling people names and talking down to them. Recently, we had a congresswoman from Arizona shot. Why?
Because of differing opinions! When you can't disagree without respect and civility, these things happens! This young man, who shot the congresswoman, was disturbed and wanted to solve a problem, but unfortunately, he took a rifle and a few died because of his decision.
