I read the Scott Adams article, and I would agree there's a little bit of nuance to the issue (I accept Trump didn't explicitly have in mind an image of torch-weilding, anti-Jewish chanting, Nazis when he said 'fine people'), but in the end the basic point is still the same. Adams is clearly bending over backwards to find a way to put a non-appalling spin on Trump's comments, but even viewed as charitably as possible those comments say something disturbing about Trump's world-view.
Trump himself talked of 'both sides'. Implying there were two sides. One of those sides was overwhelmingly Nazis and white-supremacists. It was a far-right rally. I remember from accounts at the time, before the lethal violence, that there were some there who claimed not to be actual Nazis and white-supremacists - mostly gun-nuts and militia types, about whom you can quibble as to whether they are explicitly racist or not (I think in practice those guys tend to be so, but, OK, maybe not Nazi levels, and not as a point of fundamental ideology).
But if, as Trump himself stated, there were 'two sides', then everyone on one side there was on the same side as large numbers of actual Nazis. Perhaps it's just me, but to be on the same side as Nazis strikes me as being incompatible with being a 'fine person'. And I don't think Trump really thought it through very much anyway, in terms of identifying exactly who was present, he was just reflecting his instinctive sympathy with the racist right.
Conversely, the 'other side' would have included a wide gamut of people, including I'm sure some over-excitable Antifa types, some of whom actively like punch-ups. But it clearly isn't a symmetrical situation, the proportion of 'extremists' on 'each side' was very different, plus I do not and never will, see hard-left/anarchist/antifa people, even the ones who enjoy street-fights with Nazis a bit too much, as equivalent to the far-right. Such groups have no historical track record of either murdering innocent people just for their race or other characteristics, or of taking over the state (anarchists couldn't manage to take over a boy scout picnic, as any communist will tell you).
