Not anymore sexist than the rest of Japan.

Plus it's a predominantly boy-oriented franchise. There aren't PreCure magical boys because PreCure is a predominantly girl-oriented franchise. This site hosts several men who like PreCure and a few ladies who like Rider and Sentai, and one guy who loves Ponies.

Peripheral demographics shouldn't be ignored, but they aren't going to be catered to like the target audience unless they prove a stable consumer base, i.e. like the Bronies. Sure little Japanese girls watch Toku, but more little Japanese boys do than girls and Toei will cater to the larger audience.

Plus Red always gets the better toys, even if other colors are equally worthy, like Sela the Best Shark.
