鈥淢easles was the chicken pox of my parents鈥 generation,鈥 one woman wrote on Facebook on Sunday. 鈥淭hey would have measles parties so they could catch the measles because measles is safer to have as a child.鈥

鈥淶ero deaths people. ZERO. State of emergency, forced vaccinations, bullying, mandates all for ZERO deaths and an infection they admitted we used to have normal 鈥榤easles parties鈥 for,鈥 wrote another on Saturday.
