Here's an example of what hidden #ableism can look like, that wouldn't be obvious to spot:

There's a social convention to do something a certain way. Pointing out how it works is considered rude, or otherwise socially undesirable. If you do not participate, you are disadvantaged or left out entirely.

This means you cannot ask for disability accommodations. If you *do*, you will be considered rude, get extra scrutiny, and so on - not even for being disabled, but for pointing out the social convention out loud. If you *don't* ask, you get left out entirely, because you are unable to participate on the usual terms.

Meanwhile, everybody else feels that the social convention "works", because they've never had issues with it, and they don't get why you can't just ask for help. They may not even realize that the social convention *exists*, and just go along with it because that's how they learned it.

Ableism takes many forms. This is just one example that is easily missed.
