Why is society in the US supporting obesity?

I get body positivity, but if someone is obese, we should be helping them get healthy, not telling them they perfect just the way they are. This toxic body positivity culture is going to cause tons of early deaths in the US due to weight related illnesses and side effects. I’m not saying everyone needs to be thin or strong, but weighing 200lbs when you are 5’5” is not something to be proud of. It’s literally life threatening. We might as well be telling drug addicts that they are perfect just the way they are and shouldn’t get clean just to appease others.
