Poring over family photographs, Jessica Watt Dougherty voices anguish over her father's death, Randy Watt. The 64-year-old man refused to get vaccinated and died alone in a hospital last year after struggling with Covid-19. His family discovered that he had a secret virtual life on Gab, a far-right platform that observers call a petri dish of misinformation and conspiracy theories. To his vaccinated family members, his Gab activities explained why he chose not to get inoculated against Covid-19, a decision that ultimately had fatal consequences. "I believe that there's a lot of people screaming fire in a crowded theater on gab.com," Dougherty tells AFP. "We are free to speak, but we can't speak things that are going to harm other people."
