About midway through his address to a crowd in St. Louis in late August, Greg Locke shifted gears. The goateed pastor of Global Vision Bible Church in Mount Juliet, Tennessee, had been regaling the audience -- "patriots," he called them -- with stories of defying state health recommendations by holding maskless, in-person worship services during the COVID-19 pandemic. Shouting into the microphone, Locke -- who weeks earlier denied the delta variant of the coronavirus existed -- suddenly began scolding listeners for not doing enough in the fight against pandemic restrictions.
