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.
You stop speaking to them.
They’ll either come to realize that there are real world consequences for being a dumb asshole, like their friends and family abandoning them…or they won’t. Either way, you win.
