Obesity rates of hospitalised cases might generally match national obesity rates (although I'm not sure that's true - for example in the French study the obesity rate of hospitalised patients was 70%, whereas the national obesity rate in France is only 17%), but that doesn't mean that the researchers simply "see a large portion of obese people and assume that’s a health risk", that's a ridiculous claim. First of all, obesity itself is the main proven risk factor for other observed comorbidities of covid-19 (diabetes, hypertension, cardiovascular disease, chronical inflammation); and not only that - it's pretty much a risk factor for anything health-related and a primary driver of many chronic illnesses. The article also conveniently ignores other studies from numerous countries which demonstrate that the proportion of cases that develop severe pneumonia and require mechanical ventilation is by far higher in those with obesity than in those without, even when controlled for potential confounders and independently from other comorbidities. Yes, there should be more research done and more data collected, but at this point everything points at obesity being a factor associated with a more severe course of the disease and more negative outcomes, so I'm not sure why we should pussyfoot around it based on some weird claim that such facts are somehow harmful to the obese because it creates stigma. Normalisation of obesity is what's harmful to the public health, not scientific research pointing it out as one of the risk factors.
