Jfem,
You are aware that the “consensus” medical opinion until fairly recently was that homesexuality was a “mental disorder”.
So according to you up till the diagnosis was changed everyone was to believe that it was so and if they disbelieved it they were minority “nutjobs”.
The morning after the changed diagnosis, those who disagreed became “nutjobs”.
As for questioning everything.
Not at all.
There was one truth that God gave us and attested to the fact it will never ever change.
It’s called the Torah.
