I am very prepared to get downvoted for bringing this up - but I'm not convinced that the "anti-vax movement" most people think of is truly to blame (that is, crazy people who think it gives you autism or whatever).

At least in my area, there are pockets of (relatively) new immigrants that have MMR vaccination rates at around 30% (that's very low, much lower than the anti-vaxxer population could account for imo), and the reasons for that have nothing to do with MAGA/MAHA as far as I can tell.

It's an entirely different problem (that needs solving), and pretending that this is simply the by-product of uneducated crazies on the internet feels like it's over indexing on a loud and flashy but ultimately small part of the problem.
