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.
Their bullshit causes a risk that someone else hesitate or pass on vaccination. You did an attempt at convincing. The responsible alternative is to make them feel uncomfortable bringing up the subject.
