What would a modern day Civil War look like in America?

I Envision a modern day Civil War in America being much different than the Civil War we learned about in our history books. A modern day Civil War would have many aspects to consider, first and foremost what party is in charge that party would presumably control our military, however State Governors control the National Guard in their state. Another aspect to consider would be the numerous law enforcement agencies. We have already seen this play out to some extent Chiefs of police of large cities openly rebelling against the president saying they would not enforce any laws against Sanctuary cities and on the other hand you have numerous County Sheriff's across our nation being very outspoken in support of stronger immigration policies and upholding the Second Amendment saying the citizens do have a right to bear arms and defend themselves. So the battle lines are already being drawn the coming civil war will not be between the North and the South it will be between urban and rural between liberals and conservatives they have already been waging a cyber war against one another since Obama was elected and now that Trump is in office the war on social media is at a boiling point and is spilling over onto the streets of reality. If you've been paying any attention to the news of late you have seen multiple classes in the streets of Berkeley between liberals and Trump supporters, shouting matches and standoffs at parades between the opposing sides in Oregon and Washington State. Conservatives outraged at New York mayor Bill de Blasio for allowing a parade celebrating a terrorist that Obama had freed from prison and now a senseless shooting in Virginia of conservative lawmakers practicing for a charity fundraising baseball game the shooter was a socialist Bernie Sanders supporter these incidents will become more and more prevalent as the rhetoric on both sides becomes louder and more visceral The Next Step as we spiral down this path will be Anarchy this will first become apparent in our large inner cities case and point Chicago it has pretty much reached that level already turning into Anarchy in these large cities as authorities lose control of vast areas their only resource will be too barricade them off. No one in no one out as turf wars rage gang violence will become rampid they will block off their own streets defending piles of trash trying to contain that which cannot be controlled the rural areas of our country we'll set back for a Time and watch the Cities Burn, until those in the cities have destroyed everything they can get their hands on raping robbing and pillaging one another they will then look outward trying to migrate from the cities they have left in ruin meeting a well-armed Rural America that controls the highways and byways of our nation that folks is when the Civil War will begin. My money will be on the heartland those rural Americans that grows the food that feeds this nation that is armed to the teeth that has the four wheel drive vehicles and did I mention knows how to live off of the land. Now this war will not be fought in a vacuum and I doubt that Russia, China and Islam would just sit back and watch us implode without trying to affect the outcome just another of those variables I mentioned. So it's doubtful that either side would profit from this war but I still see it as inevitable because we are trying to pull this nation and two completely opposing directions and we have demonized each other beyond the point of reconciliation. my advice is to prepare Lock and Load folks it could be a long winter!
