I find it funny that people blame social media for the state that America is in currently, when really it's the work of what Mainstream Media has been doing to us for the past 100 years. First the newspapers and then television news networks all have continued to stir up the pot to create more conflict, all while trying to subtly support whatever group of faction they wish to see win. Social media just allowed them to do it faster and more efficiently, but the root cause is the same. 

This also stems from deeper causes as well, namely collectivist indoctrination in schools and universities that makes kids think they must follow the prescribed "tribe" they are told to follow, support, love, and not question. In many ways, our issues started when we stopped following our core ideals of Life, Liberty, and the Pursuit of (one's own) Happiness, and started thinking that European philosophies held better promises of utopia, of which are totally unattainable. "You, the individual, don't know best, the group does. The Race does. The State does. The Nation does. The UN does." This cycle of collective indoctrination goes on and on... And the results are seen all too keenly in America today.

As for a civil war, well... whatever happens to us will directly affect Canada as well. You are our neighbor after all!

Tagging @whatsup since this reply is rather in depth for the whole issue
