I absolutely sympathize with individual reasons to vote Trump and don't automatically look down on Trump voters (immigration, for example). But, Trump himself and explicit "Trump supporters" (i.e. people who make it clear they support his general identity - negativity and all) 95% of the time don't leave any room for sympathy when I encounter them, online or in person, and they are extremely common. What the average liberal is shown (and I assume you care about the average person in each camp, since lauding the common man is a prominent value) is an unheard-of-in-their-lifetimes amount of verbal encouragement (with varying degrees of explicitness) for hatred of others, violence against others, imprisonment of others, and disrespecting of the law/constitution in the name of those things. It's not comparable with any past Democratic candidate (or Republican, for that matter).
On the personal scale, my wife and I don't express anything close to extremist positions, or any cheerleader-type love for Democrats, or any name-calling of conservatives, and yet we are called every slur that's popular with Trump supporters. And we're white, cis Americans. My wife, because she's so friendly when strangers talk to her, has been stalked by one Trump supporter and had another call her a slut (to another Trump supporter, not to her face). She's terrified of these people now. It's insane that they even state out loud their support for Trump in the short time we encounter them.
You can't expect humans presented with that to think, when that candidate wins, "Wow, I guess political issues X, Y, and Z are really important to those guys. Maybe I was too harsh on them." They're going to think, "Wow, those guys really are leaning in a fascist-y direction and have a big problem with evil people in their ranks. I'm scared for my country, community, and family." I don't think that's an extreme or unnecessarily provocative thing to admit.
