Well, we definitely should not pander to them.
I actually think most people (Trump supporters, you, me, everyone) vote mostly based on identity (liberal/conservative, religion, race, open-minded, well-mannered, etc). I think Trump supporters mostly voted for the party that they most identified with, the guy they thought was on their side. And I think you did the same. (I see myself as unaligned and open-minded, thus I voted for someone else as I found both sides to be extreme and closed-minded.)
But, maybe I'm wrong. Maybe most Trump supporters are horrible people. But they are still people. Like you and me, they have a dark and a noble side. And, just like you and me, they are not going to listen to the reasons of someone who insults them.
So what do we gain from demonizing them? We only lose influence.
