I think this has drifted off topic, but I’d like to point out that it’s even drifted further off than it did to begin with.
Inspiring people is a good thing, presenting a positive body image that motivates people to make changes in their life that they will benefit from is a good thing.
But that’s not what objectifying does. The word is negative because it means (in this context) to treat or reduce a person to the status of an object.
Watching super fit people being super fit is not automatically objectifying. The Olympics do not objectify the athletes and superhero movies don’t have to either.
But they can, and when they do, it’s not inspirational and it’s not something that should be ignored.
Because the people who make those movies can do better, just like the rest of us.
