Personally I would add to this that for individuals who are unable to mask, and who's struggle to mask is so to speak, "visible" to others, while they are still subjected to all of the ableiem that comes with being neurodivergent, it's almost like their inability to mask becomes a punchline for neurotypicals. I think some NTs use the joke as a way of trying to relieve the pressure to mask thinking they're being accommodating, while still addressing the disabled elephant in the room. The end result is that the person's lack of masking capacity is mistakenly correlated to their entire set of abilities - people assume they're incapable of everything. It's pretty dehumanising and infantalizing, and puts so many limitations on the opportunities available for folk who can't mask.

And on the other side of that coin, people who have the ability to mask really well are expected to do it flawlessly 24/7, and failing to do so isn't a sign that having ADHD can be disabling, no, for people who can mask, not masking 24/7 is apparently a moral failing. Which is not the kind of social expectation you want on someone who's condition predisposes them to anxiety inducing perfectionism, and leads to this expectation also being internalised.

Which occurs for both types of people - internalising the expectations. if society treats you as useless, you start to feel useless, until you fall into a pit. if society expects you to always be performing at 110%, you begin to feel like a failure if you output anything less than 109% until you burn out and fall in the same pit.

(because I don't think neurotypical people realise that masking is operating at >100%, it's an additional request on our mind and body, it's an additional labour, it's not sustainable long term. There really is the misconception that we can choose to turn it on and off at no personal cost to us.)
