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.
Every time he lies about vaccines you break one of his fingers and tell him lying is bad for his health.
Jokes aside, ask him who his doctor is, call up his doctor on speaker and ask the doctor if they’d recommend vaccines. He is almost certainly lying to you because he thinks “you believe doctors, ergo I will lie and say a doctor supports my position in an attempt to manipulate you”.
