Do men really not know women can grow body/facial hair?

Scrolling through Twitter (fuck you Elon) I saw one of the newest blow ups was over a female rabbi being labelled as trans for having PCOS (Polycystic ovary syndrome) and not shaving her face.
A lot of mostly guys were in the comments both saying that the illness doesn't exist or that "real" women can't grow facial/body hair.
I know that internet men can't speak for men as a whole, but this seems to be somewhat of a reoccurring theme in general.
Is the education system really this bad and can people really be this stupid?
