So everyone's all wound up about how biased, unpleasant and aggressive the moderators were in last night's Republican presidential debate. Why? This is who these people are. This is how they talk and think when they're alone with each other. They live in such a hermetically-sealed bubble that it's doubtful that they encounter more than a handful of people who think differently than they do in any given week.
For the moderators, this behavior was perfectly normal. I'm sure they're trying to figure out just how people think they were biased when as far as they and their friends were concerned, they were being perfectly rational.
