I have a friend who lives out in the country, so mostly I saw him on facebook. He eventually blocked me, but when he first started putting up conspiracy theories, he’d “discuss” them with me. He went from “we didn’t go to the moon” to anti-vaxxer and “crisis actors” over the course of two years. In one of the last drag-outs about vaccines, I showed him the numbers, I showed him tombstones from 100 years ago when kids died young, it didn’t matter. The only numbers he accepted were the anectodal stories of people who got their kids their shots, then believed they became autistic due to it.
I kept asking, what about the 40,000 people a year who died of measles before the MMR vaccine began? He literally said, “I don’t know about those”. But somehow, he did know of Bill Gates’ secret plan to “reduce population”. There is no way to win that argument. Facts are irrelevant. You can only lose by doing what Dilbert does in the next to last frame.
