What you are hearing and seeing is the civility and uniting abilities of Obama hard at work. Was there ever a time in the past 100 years where more division was evident? Divide and conquer is the path to the destruction of this country as we know it. Obama and his democratic partners are well on their way and the sad part is most of them don’t even realize how they are being used. Who will gain when the destruction is complete? Those in power will live the “good” life and the rest will be subjected to their whims. Ayn Rand was right and “Atlas shrugs”. It may already be too late to turn the tide.
There was more racial division and violence from the 60s-80s in the urban northeast and Urban upper Midwest, but other than that your points are well taken.
