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.
This is the answer.
You can’t reason someone out of an unreasonable position.
The only response is to ask them what evidence they would require to change their position.
They’ll inevitably reveal that their assertions are merely beliefs because it’s not practically possible to prove nor disprove them.
