My ex husband had severe handwriting issues. He was a cis het white male with a serious career. He was able to use his favorite pen, among other things, without needing a label -- like dysgraphia -- to qualify for accommodation.
Both of our sons were labeled as having dysgraphia. They needed the label to get accommodation in public school.
We eventually pulled them out and homeschooled. I have formal diagnoses for some of their issues in part because of the time they spent in school. But I don't have formal labels for everything, in part because I no longer needed a formal label to accommodate a thing while homeschooling.
Their dad did everything in his power to insist his problems were not like the problems his children had. I saw this in other parents who had children with labels.
I recently posted a thing to HN that got no traction. Some years ago, Microsoft did a study designed to investigate limitations without using words like disabled or handicapped. It found that about 60% of respondents had difficulties with day-to-day tasks if you just asked about tasks without using stigmatizing labels, like disabled. In contrast, only 15% to 20% of people self identify as disabled.
Findings:

People who self identify as disabled get very up in arms about "normal" people using, for example, "Spoonie" language. So both those who self identify as disabled and those who don't are equally touchy about such things. They want some clear dividing line that may not genuinely exist.
I'm "Twice Exceptional." I'm gifted and disabled.
Various groups, such as gifted students or men able to claim male privilege, are able to get a lot of accommodation for their preferences with a non stigmatizing label. Their position of privilege gets them the best of both worlds.
I strongly suspect that a lot of people use privilege to demand accommodation for mild to moderate disabilities while side stepping the stigmatizing label of "disabled."
I think there's a lot of other stuff going on, more than I'm going to fit into a single comment. But, in a nutshell, if we lived in a world that more consistently let you go with your personal preferences without needing a justification, we wouldn't battle nearly so much over such labels.
(Yes, I know: Sometimes it's important for things to be done X way. But it often really isn't and what happens is privileged people wind up free to do whatever and underprivileged people get their lives turned upside down on silly excuses, basically.)
