My liberal boomer parents are trying to convince me, a healthy 30 year old, that I need a covid booster shot. They actually believe that the cdc has said everyone needs to get a booster shot. They also refuse to leave their house without a mask on and they thoroughly disinfect every single thing they buy, including washing all their food with dish detergent. They believe all of these things "because of science". How do I deprogram all the propaganda out of them?
