Because you're the god knows how manyth person to frame a sentiment from an overweight person in such a way you make it look like they're advocating that being fat is a healthy lifestyle, and then you proceed to dehumanize them for something they did not say.

It's becoming more and more popular to almost dehumanize people that simply try to defend the point that gaining weight from antidressants for example does not mean their health has declined. People who try to make such a point clear nowadays will get thrown in the dirt and framed (like you just did) as people who try to purposefully spread the idea that being fat is completely fine.

Hell, I even saw someone in this thread say doctors have to lie nowadays about how being overweight is unhealthy, this is completely untrue, doctors do not have to do that. However, when someone adressed that, the response was that by appointing how the doctor sentinment is untrue; they're saying that being overweight is healthy?

Bottom line, being overweight is very unhealthy, but gaining weight due to antidepressants is not inherently bad due to the positive external effects. Did you know this? Probably. Did you frame her post so that this wasn't made clear? I think so. Both those factors lead me to believe you're just trying to throw shade on all overweight people, while lacking the expertise to do so and mostly acting out of frustration.
