It’s pretty common on the right.
I don’t understand it, but I see it all the time. They absolutely refuse to admit to a mistake, and in the unlikely chance that they do, they then claim that that mistake will be held over them.
Now, it’s entirely possible that it will be, that people on the right hold such high contempt for error, but over here on the left, it’s more forgiving. While I will happily hound someone for making a mistake they won’t admit to, once they do, then there’s no reason to continue, they’ve learned and grown. But they think that admitting to a mistake is something that will be held over their heads forever.
As an example:
I actually thought that we were making pretty good progress, and working towards a mutual understanding.
Then he pulls that, and I’m left wondering why. Is it something that he would do? If not, why does he think that others would?
So much of the right’s performance isn’t in reaction to what anyone has done, it’s in reaction to what they think others will do, and they seem to use what they would do as that benchmark.
Honestly, that last line probably taught me more about right wing grievance mentality than the proposed thread would have.
