Mark Levin: Just think, in the last few weeks the Left has ruined the NFL, late night TV, and the Boy Scouts. In the last few years they’ve severely damaged campus free speech and academic freedom, the private health care market, military readiness, and local law enforcement. Their judges have seized control over immigration, aspects of national security, and marriage. Meanwhile, the Left is increasingly violent (Antifa, Black Lives Matter, etc.) and the media are increasingly brazen in their leftist propagandizing and cheerleading. It seems to me the rest of us should be taking a knee to protest this insanity.
