They are citing ONS figures of excess deaths as proof the vaccines are killing people. I tried to explain that not being able to get a doctor’s appointment, staying home and getting fat, etc explain the figures (official sources have said it too) but they said it’s “gaslighting” and then said their family doctor wouldn’t get the vaccine.
Not everything requires a response and at some point you have to pick your battles. They have revealed to you that they are an idiot. It is not your job to fix them.
