Or what would that be called? Pretty much the same things that would usually be considered ableism, but when there’s not a recognised disability involved but just health issue/s (which could be “disabling”).
For example, not believing someone about their health issue, dismissing it or refusing to believe that it impacts their ability to function or can be a valid excuse for things (often solely on the basis that it’s not a recognised disability), blaming someone’s health issue on different things they aren’t caused by (and trying to attribute it to the person’s behaviour as if it’s their fault), and/or claiming that their opinions can’t be taken seriously due to their health problem
Would it be called health-based discrimination or something (despite somewhat mimicking the same mentalities as ableism)?
able·ism /ˈābəˌlizəm/ noun A system of assigning value to people’s bodies and minds based on societally constructed ideas of normalcy, productivity, desirability, intelligence, excellence, and fitness. These constructed ideas are deeply rooted in eugenics, anti-Blackness, misogyny, colonialism, imperialism, and capitalism. This systemic oppression that leads to people and society determining people’s value based on their culture, age, language, appearance, religion, birth or living place, “health/wellness”, and/or their ability to satisfactorily re/produce, “excel” and “behave.” You do not have to be disabled to experience ableism.
This is also tied to healthism/health supremacy, recommended researching more about these topics to better understand how they impact everyone’s lives, disabled or not.
