The main lesson learned from Trump's campaign is that "rational" is far less important than "belief" and "story".
Here's what seems irrational from my perspective:
1. Bob votes to elect Mike Pence, who takes the position "Homosexuality is incompatible with military service" [mikepence.com]
2. Dan, who is homosexual and in the military and Facebook friends with Bob since they started hanging out in college, finds out Bob voted for Mike Pence.
3. Dan says to Bob, "Yo man, that's pretty bigoted of you to vote for that guy."
4. Bob says I'm not a bigot.
5. Bob doesn't empathize with Dan or understand that Dan is really just pissed Bob took away his ability to serve the country in the military by electing Mike Pence.
