Yeah, it’s a sterile medical term that unfortunately takes on other meanings that people dislike. For example, I had a friend who went off the deep end and started claiming that obesity was made up by doctors and began trying to convince me to think likewise. It was kind of eerie to see this otherwise rational person fall for this type of denial over something that made them uncomfortable.
It doesn’t help that some doctors were shitty to him about his weight (a fair and very real complaint) so he insisted it was a systematic problem within the medical establishment to oppress. I don’t doubt it happens but it’s a bit extreme to think it’s solely used to that end and that it’s not a handy label for managing weight and conducting research.
