I'm not really sure what you're trying to say here. How and why does one have a "predefined" opinion? My opinion of the guy was formed by watching the guy's behaviour over the years. How else would you suggest I form an opinion about him?

I watched his "stand back and stand by" comment in context as well, and if it doesn't strike you as an extraordinarily odd and specific request to make of a group of people he has allegedly never heard of, I don't know what to tell you. It seems incredibly unlikely that Biden (who I also criticise in the article by the way) would have made the same comment.

I have no reason to want to believe anything about Trump or anybody else, but it would be incredibly easy to make the case that the people who support him despite his countless well-documented lies, his disastrous, openly dishonest handling of the pandemic, and his embarrasing attempts to undermine the election, are the ones who are believing what they want to believe.
