So, my partner is disabled - he has very severe osteo arthritis and will need a knee replacement soon. He is involved in a few disability action groups. So I'm imagining a 'disability-fest' where an event is planned to talk about ways to celebrate your crutches or stick, because some people (dp included) can feel embarrassed about using them and this can affect their life and self perception negatively.
Then some wheelchair users declare that they find this activity violent and exclusionary because they are unable to walk at all. And so the organisers cancel it with apologies, in order to be inclusive.
I think non-disabled (or trans-disabled ... there are people who feel their functioning legs aren't truly part of their body, after all ) people complaining about feeling excluded by talk of crutches would be a better comparison here.
But other than that, you hit the nail on the head.
I never heard of women with PCOS complaining about anything done to celebrate menstruation, even though there are some for whom menstruation is very painful, and some for whom it is not regular. Older women, likewise, never complain.
There's also women who don't have legs (but don't complain about celebration of leg hair), women who don't have breasts anymore (but don't complain if other women walk around topless or celebrate their breasts in any way) women whose genitals were mutilated (shouldn't they be the first ones to complain about feeling excluded by the celebration of normal vulvas?), and so on and so forth.
