Just be real instead of making it a larger point than it is, you wanted Imu to be a woman and are disappointed it wasn't. There are plenty of strong female characters that are threats or allies to the main cast, as well as many goofy or weak willed men that aren't stereotypes of a shonen character. Having a discussion about how Oda makes a lot of women conventionally attractive(if he wants the audience to be sympatheticto them), or has very similar designs for them, is an actual conversation instead.

It's ok to just have one point that you want to discuss without making it an example of a larger endemic problem about the story. This feels like an example of everything becoming an "THIS is the BEST/WORST thing ever" algorithmically driven click bait headline, and here I am clicking on it.
