I would counter by saying there is definitely group think on the right. There are people who are going to support Trump no matter what, and are not open to debating his spending, criminal activities, Covid policies, etc.
But if you’re purely blaming the right for the development of an “infotainment” industry and implying only the right is gullible, then we disagree. The left just happens to fall more in line with what big moneyed interests are pushing these days, so the right may seem intentionally more fringe.
