I'm not the person you responded to, but here's my take.

I can respect someone I personally dislike. I can also respect someone who disagrees with me. I can even respect someone who makes my life harder, though I might dislike them for it.

But I lose respect for a person for many other things.

Once you tally up all of the factors, I do have trouble respecting most of the Trump voters I've personally encountered so far (not many) because I sensed too much intellectual laziness or cognitive dissonance.

Once you tally up all of the factors, I'm not sure that Trump voters come out ahead of non-voters in aggregate.
