With all the internet and other forms of news and media today it's not hard to assess that Trump is considered a hated man.
However many forget to read history books. James Buchanan, our 15th President, would likely be the current title holder of "Worst US President in History"
He paved the way for the South to Secede from the Union and once Lincoln became President, nobody heard a peep out of Buchanan, not to mention his predecessors, Franklin Pierce, Millard Fillmore, and John Tyler were also not helping the crisis in the South during the mid to late 1840s.
If we're to go to civil war in this day and age, it will mostly be based on Political Hypocrisy and wouldn't have a side vs side viewpoint. At that it would also be the dumbest thing to ever happen, our international enemies WILL capitalize on that opportunity. Trump isn't the worst president, you can bet on that
