I’d argue that mainstream libs represent the segment of the population that still hasn’t been significantly affected materially. They still have their jobs, they can pay their bills, and there really hasn’t been any dramatic change in their lifestyle. They also tend to stay in their bubble avoiding interaction with people who are struggling. This segment of the population is rapidly shrinking though, and we can see them starting to freaking out that their voices are increasingly challenged nowadays. It’s a huge shock for them that their narrative can’t spread unchallenged.
