This is typical of a tribal supporter with inbedded hatred of other side who is wholly incapable of objective thinking.
There are a minority here who think every Labour leader is great, every Conservative and policy is terrible, who will always jump to defence of one and attack the other, and nothing can pierce that pre decided closed position.
It's called "confirmation bias"
Absolutely this. Its a fascinating study into the human psyche and one I can never get my head around. For example if the Tory party mandate was what I thought best for this country at the time I would vote for it. In the last election I thought change (however painful) is the right thing for this country, so I voted for it. But there are those amongst us (and on here) who probably do think like that, but then can't action it due to the blue red bias they have going on...
Its like this:
Would you let Trump be your childs teacher? No
Would you let Trump anywhere near your daughter? Take her out for dinner? No
Do you think Presidents need to be good role models? Yes
Should convicted criminals be Presidents? No
Do you think Trump tells the Truth? No
Is Trump Racist? Yes
Will you vote for Trump? Yes
Why? Don't know
Its something that fascinates me greatly, including how people vote for dictators and fascists as you point out...
So many things go into winning an election in a democracy....
