Its seems like this to me. People thought there were loads more Autistic men than women for years. In fact it was seen as a male condition, because female autistic people often present differently. One of the hypothesis around why this is, is that females, in general, are far more "wired" to work very hard to fit in socially, and thus we tend to be better at mimicking, masking and generally being fairly invisible, as autistic peopleI respect your intent to explain and seek validity for yourself. I just think the generalization is unhelpful toward that goal. It also invalidates other people. If I said most black people were ignorant, but this doesn't apply to all of them, would that be a worse statement?
I'm also confused about generalizing as a way of explaining things aren't the same for everyone. That sounds contradictory.
In my case, I am 50 and just recently received confirmation of my autism because of how I've gone about being invisible, as a child (a very quiet, bookish girl, who hid in the library at school) and then an abused (by a man twice my age) teen mum who learnt how to talk to people via performance art and who hid behind my role as a mother of a large family.
As a "late diagnosed" female autist, (and I'm diagnoses as ASD2 mind you), with both sides of my family showing autistic traits and having subsequent generations of children getting diagnosed, I didn't inherent a small dose of the auties.
Being female and working EXTREMELY hard to "go under the radar" is not at all uncommon, in comparison to the majority of males. Not all, but many. My youngest sons are much like me, but my second oldest is very noticeably autistic
