You still don't get it. The scale of what is important to you can be different to what is important to others. It's not simply whether any one reason is rational or not, it's that they are not all weighted equally and consistently by everyone
Of course I recognize that. However this does not mean all weightings of what is important are equally rational. I can't consistently think that I have objective, rational reasons to think Trump is disqualified to be president in a way no other candidate I can think of has been (this, by the way, include Nixon who at least was rational and made good decisions) and at the same time think that a coal-miner in the middle of America does not have access to those same reasons.
Sure, we can say that this coal-miner because he is a coal-miner simply must vote trump because HRC supporters say mean thing about him, but that is not a rational reason for voting Trump and I think it is depriving him of basic agency.
I will put it like this: If HRC spend all her day saying that my particular social class was trash, and Trump spend all day saying my particular social class was the best, that would still not provide a rational reason to vote Trump because he remains a much more flawed candidate.
