I live in Europe. For employment that demands physical stamina it makes sense that fat people would not be favoured at the extreme level of obesity. My healthcare provider differentiates between overweight and obese and you can't treat triage as discrimination. There's a whole lot of middle ground between staying in your home not eating cake and promoting yourself on Instagram. Date and dance as you see fit.
The kind of discrimination I am talking about is refusing to hire fat people for desk jobs (or not promoting them, or paying them less) because of stereotypes that they are lazy or lack self-discipline or simple distaste for the way they look. [1]
Categorizing a patient as overweight or obese is not discrimination. Dismissing their health concerns or providing lower-quality care because they are fat is. [2]
