One important thing that the essay doesn't mention is that our current orthodoxy isn't democratic. The orthodoxy is dictated by newspapers and universities, with some help from Hollywood and tech companies. None of those institutions are remotely democratic (if they were, they wouldn't be so strongly aligned with the left). Perhaps we need to establish some limitations on what people are allowed to say, but if so, those limits must be decided by formal democratic processes.
