I thought- this is a new form of gaslighting- refusing to acknowledge physical pain,
It's very common in Germany in my experience, I mean: It has a past, a present and it will have a future.
I was and am psychopathologized regularly, i.e. people claim that my physical symptoms have a psychological cause.
The problem you describe is sth that honestly troubles me a bit. It reminds me of religious fanatism: If you're not a believer, you will be "flogged". It belongs to a wider problem in my view: We have unlearnt discussions and accepting other opinions. Instead, only one narrative is allowed, and if you don't follow there will be "hatespeech".
Fanatism means: no matter how many facts you present, they are ignored or discussed away.
Respect for speaking up - we need that! It takes a lot of courage though.
