I was not suggesting you were making light of catching covid. I was acknowledging and joining in your little joke.
I never claimed this is the only step I take towards not killing my grandparents. Nor that that’s the only benefit I or the people around me get from my being vaccinated. I also wear a seatbelt and don’t drive drunk, but stating that doesn’t mean I’m claiming I am thus immune from car crashes.
Either you don’t know what the word “disingenuous” means, or you’re just being rude.
