The title on this is a serious misnomer. The topic is unmasking in general, leading perspective, (male, pretty singularly from the speaker's sole perspective), a trait found in most autistics. The singular fixed perspective and missing (real female context) is another illustrated trait of autism. Lots of decent information, but not when relating to female unmasking...
If one wants to talk about unmasking in females specifically and the biases inherently associated with it, listen to female autistics, don't assume that information while presented by an autistic (male) is accurate in any stretch of the imagination.
Masking is universal across the spectrum, but females are generally more adept at it simply because of how we are raised and the social expectations that often accompany our gender. Female autistics are not making assumptions about their unmasking because they are living, primary sources of real world information.
A question and answer format featuring a female autistic with a male vs. female compare and contrast trait side by side probably would have been a more effective way to go.
My hyperspecific critique on failure to effectively connect the title to the topic is very definitely one of my autistics traits. Female autistics tend to lean toward hyperlexia. We can often read by a young age and learn to speak early in development.
The sway toward these hyperdeveloped skills are the basis for our masking skills as we grow. We can wield language like a shield and as children will practice different facial expressions in front of a mirror. We can often be very responsive to the emotions of others and can be labeled as high strung or highly sensitive. We often jive much better with adults than with our peers.
Physical appearance also plays a significant role in the preceptions of others. If you know how to dress well, speak well, and possess regular features people never assume you have issues. Things like knowledge gaps or struggles with simple tasks like remembering to renew your car tabs or going to pieces when you cannot get your allergy medication refilled before you run out seem like aberrations in an otherwise highly capable adult.
In cases when dealing with selective mutism due to an overwhelming situation, people assume that you are angry or pouting, rather than in the middle of a sensory shutdown. It isn't that you don't want to speak up and clarify; it is quite simply that you cannot. Your hyperlexic brain is frozen and needs to reboot. The need to escape the situation can leave you with labels of snobbish or selfish.
Migraines (often from a young age) are a very common occurrence, generally stemming from sensory triggers that overwhelm a divergent nervous system. Food proclivities and physical clumsiness are often present as well. While not diagnostic criteria, they are definitely subtle, but notable traits that can indicate autism in a female.
One of the best resources I've found on female autistics, by a female autistic is The Divergent Mind by Jenara Nerenberg.
