I'm willing to bet there's some guy who was stupid enough to be anti vaxx or ableist because they saw a post saying some "vaccines cause autism" bullshit from a 67 y/o named Linda or Janet who they met on Facebook and they believed it cus why look stuff up and do research before putting out stupid claims when the person who said it clearly has a middle school graduation certificate so they must be smart enough to know what they're talking about and the chain continues and someone else who is also really stupid, sees that same exact post, thinks the same exact thing, and that's how they're born (I'm convinced all of the people in our society who confidently say stupid shit had no education and got all the stuff they know from straight cis white assholes on facebook) Also if they're that dumb they probably aren't smart enough to read a book (or read at all for that matter)
