I'm not voxl, but I do want to point out that he didn't declare anyone evil. He declared an action evil (the action of voting for Donald Trump).

That's an important distinction to me because I believe people can change and start choosing better actions.

But, a whole lot of people haven't changed, still support Trump, and until that changes, those people are dangerous.

And sure, we can empathize with the reasons that got them to do that, but it doesn't follow that we should just pretend what they did was okay, especially is they continue to do harmful things.
