Liz, it is not only educational. I am sure that the schools and the education in the UK and in the US and wherever, are at least decent. Personally, I don't even think lack of education is the main culprit.
What is certain is that identity politics play an important role. Meaning that anti-wax and probably also anti-trans is a way of identification, a bit like saying "We who are X believe <item of interest>" . You can insert your free choice of political- or moral identity at X and your free choice of item of interest.
Of course, social media plays a very important role here. It will expose us to the things that both affirms and enforces our beliefs and the things that make us reluctant to look at it from another angle.
Idenity politics, distrust of authorities, social media, ... they go hand in hand. If we ask the anti-waxers why they distrust pharma but don't distrust RFK, then I don't think they have an answer that makes sense to us (but it makes sense to them, of course).
But SMH is also my feeling about all of this.
