There have been arguments over the direction the country should take since the founding of the republic. One of the bitterest political rivalries involved John Adams and Thomas Jefferson. Although they disagreed vociferously politically and were estranged for years, they resumed their friendship and correspondence eventually and died on the same day - coincidentally - Independence Day. (As did James Monroe).
There have been several presidents loathed by the opposition. However, until the current presidential administration, the differences have, for the most part, been resolved through subsequent elections. Whether one hates, tolerates, disdains or loves Donald J. Trump, he was a duly elected president of the USA according to the law of the land and the Constitution. He has not destroyed the country. There are too many checks and balances for any executive to do so.
Consider that Mr. Dershowitz, who admittedly voted for Hillary Clinton and argued that Bill Clinton should not have been impeached for perjury, also represents Donald Trump in this impeachment trial before the Senate and argues that he has not committed am impeachable offense. Mr. Dershowitz in a constitutional scholar with which I have not always agreed. But he is not partisan in this matter. He is consistent.
The American electorate has reached a partisan divide in which those on opposite sides of the political spectrum will not listen to any alternative views. The partisans have become entrenched in a position, will not consider any other perspective, refuse to listen to alternative views, ridicule the opposition, and argue that Donald Trump is Satan personified. I am dumbfounded by the energy that people invest in the vitriol. The republic survived James Buchanan, Warren G. Harding, Franklin Pierce, Millard Fillmore, Woodrow Wilson and Jimmy Carter (when I lived in Europe during the Carter administration I let people think I was Canadian). The republic will survive Donald Trump. We do not need our presidents to be good people. We need them to be effective leaders. John F. Kennedy is often looked upon as an effective president, yet he was a terribly unfaithful husband, violated his own sanctions against Cuba, and engaged in foreign policy decisions that were clearly ill-advised. Not only that, he accelerated our involvement in Vietnam.
I am neither a Democrat or a Republican, although I am conservative fiscally and on Constitutional issues such as the 2nd Amendment. I lean toward Libertarian, which believes in a small government that keeps its paws out of my pocket, off my land, out of my house, without any input in decisions between me and my physician, who I can marry, what I can cultivate and how I defend myself. I believe that one can love, live, conduct business with and worship as one feels is appropriate without government oversight. Just fix my roads, bridges, air traffic control, monetary policy, interstate infrastructure, waterways, borders, print money, maintain federal land, maintain our military to protect and defend the USA, ensure the Native Americans and veterans are treated fairly, and sustain compliance with the Constitution. Stay out of healthcare, insurance, education, personal life decisions, etc.
Just let go of the angst, the divisiveness, and vitriol. Embrace your fellow citizen and agree that it is okay to disagree without judgment.
