Yes, we should all be concerned about the state of American politics and how the political discourse has trickled down to everyday Americans in the forms of heightened harassment and hate crimes against sexual minorities and people of color. If our leaders want to bring the people together, they must disavow hateful language.
The political discourse in America has become empty, meaningless repetition of talking points. It is becoming more and more difficult to have an open, honest dialog about issues. Instead there are heated accusations that one side is uniformed, the other naive. This kind of talk shuts down any hope of getting someone else to understand or even agree with your opinion and denigrates the importance of citizenship.
Every round of American politics, the losers compare the winners to Nazi. The right claims that the left is communist while the left claims that the right is going go put people in concentration camps. It has never, ever come true. This is just fear mongering from people who cannot handle not getting their way.
Look at the campaigns from the 19th century and you will see plenty of examples of hyperbole. Lies and innuendos were spread in the papers and on the stump. Politics has always been a rough business. At least today we do not have Congressmen going onto the House Floor and beating fellow congressmen with canes.
