I'm going to agree with most everything here, though guys have their own critiques to deal with. Short, bald, and pudgy or scrawny muscles take a fair bit of confidence to overcome. Some compensate in more or less healthy ways depending on their own persona.

The way we deal with it as a society is a tougher question. Kids don't deal in nuance so well so trying to frame it as a health thing is hard to do without perpetuating old stereotypes. Telling them that it's wrong to bully someone but that being sedentary and out of shape is not good at the same time takes a lot of balancing. With the current culture of body positivity and health-at-every-size it can leave people scared to suggest that someone take up some sports or eat healthy for fear of being labeled as fat phobic.

Somewhat ironic additional note, I just recently joined the ranks of the spectacled. Not delayed out of vanity but out of lack of need up until now, but yes I do remember the era of 4-eyes being a thing.
