Two sides of the Same Coin?

A new president comes into power, marking a definite change from the previous one, sparking protests nationwide, that spill over into loud, almost violent town hall meetings with members of congress.  Am I talking about the Trump administration?  Yes, but I could also be talking about what happened in 2009 when the so called Tea Party movement targeted President Obama and the passage of the Affordable Care Act.
Above are two pictures: one of the Tea Party in 2009, the other taken less that a month ago.  Although the signs may be different, the anger is the same.  In fact, the similarities are striking: in 2009, rumors were spread by Democrats saying that the Tea Party was funded mostly by the conservative billionaire Koke Brothers, now Republicans are saying that Anti-Trump protestors are being paid by progressive billionaire George Soros.   Both sides embrace the expression "not my president", as if a president they disagree with is somehow invalid.  Both sides often not so subtly use Nazi imagery in making their point against whomever they disagree with.   And just as some people in Texas flirted with the idea of seceding from the country during the Obama years, now California is considering the same thing under Trump.
As a progressive myself, I know which side my sympathies lie with, but the anger both sides express reveals a sad, bitter truth about just how divided this country is.  Progressives and conservatives now live in not only separate red and blue states, but separate communities within those states.  And the media they consume only echoes their own feelings about the world.  It is entirely possible in the US to encase oneself in a cocoon in which only people you agree with ever enter, except for a few angry holiday dinners.
Americans have to accept one undeniable fact: however you voted in the last presidential election, over sixty million of your fellow countrymen voted in the opposite  direction.  It's become a cliche for news reporters to say this, but it's true: we are a deeply divided nation, in fact the divide right now has not been this strong since the Civil War.  While clearly the notions of outright warfare or California succeeding are extreme, it does often seem that red states and blue states contain people with such radically different world views that nation wide unification on many important issues is almost impossible.
So what can we do?  Well,  part of the reason Trump won is the fear of white Americans of the demographic changes the country is going through, which will eventually result in white people no longer making up over fifty percent of the country.  (Yes, even if Trump gets his wall and deports eleven million people, it will still happen).    What is going on now in the US  may be a repeat of what happened in the state of California in 1995, when Governor Pete Wilson strongly ran against immigration, running race baiting political TV ads about undocumented immigrants that Trump echoed in his campaign.  While Wilson won his reelection, the backlash against the Republican party was so strong in the state that now Democrats run almost all the wheels of power.  So, it appears that time is on the side of progressives, with America slowly but surely turning to the left as older white conservatives die off, to be replaced by a more diverse and progressive generation.  Looked at this way, the Trump victory will probably be remembered as the last gasp of the older white Americans fighting the inevitable.
