So, I'll try to respond as someone who voted in support of Johnson, and can get the appeal of Trump as well as the Clinton, as well as visceral hatred of either.
I get that huge swaths of the electorate feel like this system hasn't been working, and that' it's all manipulated by career political insiders who have their own brand of benevolent authoritarianism. I get the distrust of a liberal culture that overvalues its own contributions to society, and has a false sense of how correct they are and why they are where they are, and overlooks their own serious problems and prejudices. I understand how the media plays into this, and believe that a lot of what Trump has said has been taken too seriously or distorted, that he was projecting a character rather than an argument, and in doing so, demonstrated empathy with a huge group of the population. I get that population has been so screwed by the current system they just want something different, whether that be Sanders or Trump.
However, I strongly believe that there's a false equivalence in these discussions, and that calls for "reasoned debate" on the American right are often intentionally or unintentionally meant as a negotiating tactic, to cover up arrogant intransigence on their part. They don't get what they want, so rather than contributing something constructive, they accuse the left of "not having a reasoned discussion" or not "compromising." When the GOP and Trump talk about the left "not compromising," they're really meaning "we're not getting what we want."
Relatedly, do you really believe that the things that Trump has said about minorities, women, and so forth are acceptable ways of leading the United States, or treating those who disagreed with you? What would the GOP do if the liberal candidate said the same things about Trump?
Which party shut down congress repeatedly rather than have a reasoned discussion? Which party has been obstructing and crippling the supreme court because they didn't get their way?
The reality is that the GOP lost this election in terms of votes, and yet are still entering the white house because of a broken electoral voting system. Like it or not, Clinton won more votes than Trump. So Trump and the GOP are going to undo everything the majority voted for to get their selfish agenda, because they don't care about the majority of the electorate that voted for someone else.
Who is being unreasonable in this situation? It's not the liberal party.
I have plenty of reasons to be angry with both parties, but Trump is dangerous in a way that Clinton was not. Sure, I could find some bright sides to his ticket, but it's overshadowed by a lot to be terrified by.
