"The only one behaving mentally ill about this is yourself - tell me, who screeches at someone about declining a useless and pointless medical procedure? It sure as fuck isn't someone who is mentally healthy." Fuck the lot of them - if they are that brainwashed and stupid, they aren't worth associating with anyway. The joke will be on them when they realise they will be tethered to the eternal treadmill of booster shots.
