I'm very happy I have very little real-life experience with any of the anti-vax idiocy, and that it wasn't really a big thing in my country. Seeing all of the conservative 'muricans loose their minds over it has been both hilarious and frightening.
We still see occasional clubhouse rallies on the side of the street here in my city. They don't even know what they're protesting anymore, and are now waving both US and Russian flags. We're Canadian. My wife and I like to appear visibly laughing whenever we pass by. Sometimes I fantasize about having a device on the side of my car that launches a hornet's nest in their general direction, but I don't think they make those.
