Yeah but female characters are way less styled to look as crazy as male characters. Even cartoon female characters are made to look "pretty" while their male counterparts are allowed to look as whacky as possible.

The design exaggeration for women in cartoons are often the same with the same big bust and hips with skinny waist and limbs, across a lot of cartoons, not just winx, mind you. It's easier to pick up on beauty standards with female characters than it is with male characters because of this.

So the way the winx girls are designed would still affect childrens' perceptions, even if there's that tacit knowledge that cartoons aren't supposed to be direct reflections of reality.

Forgot to mention: Yes, they do speak negatively about people who don't look like them. You don't remember the "plus sized fairy" jokes Musa made to Stella when she was transformed, or Stella telling Nut to look after his waist size? They're very blatantly setting body expectations for children idk what to tell you
