In the end, facts are useless. You belief what you think your social bubble, and in particular, the group you think you belong to, is thinking. And many people do not speak up. Mostly those with strong (often selfish) interests speak up, and often in a manipulative way. Having narcissist or sociopaths as leader can indeed be a bad thing. Some sort of media control is good, to protect core values, to protect the law against mass manipulation.
