Living in a swing state puts me in front of quite a few Trump supporters and Clinton supporters. I haven't met any intolerant Trump or Clinton supporters yet, so I'm not sure it's fair to generalize either group as intolerant. They must exist in some capacity, but it's far from the norm, at least around here.

I don't really take internet forums as any indication of the norm, as they tend to draw extremists from both sides. Most people don't browse political forums all day or comment on news articles (I can't cite this, but I can research it if you doubt the claim), so I don't connect dots between them and the general voters. They certainly don't represent the people I know in person.
