>>Can Trump Stop the Hatred Between the Left and the Right?
We'd be guessing on that - but we have his previous four years as president to use as precedent (see what I did there? :-) ).
Using that as an example, the answer is very clearly a hard 'no' - but now with a good bit more resentment from those people who did not vote for him thrown in, just given the promises of 'retribution' that came out of his campaign - and that Trump voters can't claim they had no idea what they were voting for.
Your article seems to be hopeful that "we can disagree but still be friends", to which I'd answer, just wait, see what happens.
