Somewhere between 1 and 60,000,000 people are dissatisfied with our current president and there is always in-fighting in parties and between parties. We're mostly unified on paper, not in practice.
This isn't new though, and we had basically the same disputes when our country was founded, except it was Federalists versus Jeffersonian Republicans. It's been over
threetwo hundred years and we still haven't decided whether the US should use big or small government, and which to what extent. It will never be solved and it'll always be a sort of tug-of-war between both ideologies, but as long as we don't start a Civil War over it, we should be fine.
I want to believe you're right about the culture of outrage being a passing trend.
I lived in a pretty insular liberal community for many years, and the whole culture of outrage is basically a lack of understanding on both sides. Liberals by-and-large do not understand that prematurely labeling people as national socialists and tribals effectively terminates any chance of a productive dialog happening (this is something I admit to being guilty of myself). On the other hand, conservatives can't seem to tell the difference between trendy Tumblr SJWs - versus people who are activists because their rights are at stake. Both these problems prevent people from peaceably solving these issues since both extremes are too quick to label the other as tribal or SJW.
I do think it's a passing trend because I think that liberals will have to reassess their tactics in the next four years. We're pretty bad at winning local elections, and our party establishment gave an unfair edge to a candidate that was probably the most unpopular among Democrats. What we're doing isn't working.
