I used to believe the “they aren’t all hacks thing” until I met more chiropractors. While I would like to believe that there’s a subset of them out there who treat it more like a science of doing adjustments and what not, I don’t think that’s actually the case. My mom works for a chiropractor and has gone to several of their conventions over the years, and from what it sounds like they are all nutjobs who believe aligning your spine will cure you of all disease.
I would really love to see the numbers of how many chiropractors are antivaxxers. I bet it’s in the high 90%.
