>> They decided that the opposite of the word “guys” was not “girls,” and that they would use the word “women.” >Unfortunate quirk that guys is fine, but girls is condescending and women sounds awkwardly formal. I found that kind of odd. I would never have said the complement (calling it opposite is weird) of "guys" is "girls". It's "gals". People will look at you funny if you say "guys and women".
