Wow, it's like people are just trying to construct reasons to get upset these days.
For many if not most people, that body in the picture is not even unrealistic per se. A comparable sportiness is very achieveable if we put enough effort into it.
Of course we don't, because.. well who likes to gym 7 days a week. But that's our own choice, and maybe it doesn't hurt to be reminded of ideal goals we can strive for.
But of course, these days we'all victims, aren't we. It's not my fault if I'm fat and/or too lazy to do sports more often, it's the society's fault for setting "unrealistic" standards.
When some university advertises their physics degree with a picture of Einstein, I don't start rioting on Twitter because I'll never become a physics genius myself.
When parents tell their kid it can be president or fly to the moon someday, I won't start a campaign against them because that'll never happen either.
Usually, it doesn't hurt to set high standards and then start trying to reach them step by step. No, maybe I won't end up inventing the theory of relativity while governing the United States from the moon, but I'll probably end up having achieved more on my way trying than I had if I hadn't had any motivation or unrealistic targets when I started.
Or I just ask for all desirable goals and ideals to be removed, and demand ads to only show average joes anymore. Than I won't have to change or strive for anything, how comfortable.
