I don't think the word "kata" by itself is masculine or aggressive but the site is called codeWARs, and they call signing up "enlisting" so ..
So they better change their entire branding!

Seriously? You never noticed that the martial arts world is male dominated in a way that many women find off-putting? Sure, some women are okay with it, but that doesn't mean all women are (or should be).
As someone who has studied martial arts for five years, there have been plenty of female students and the vast majority of the people I study with are well into their 30s.
