How is this any different to what any halfway evolved human being is already doing? I refuse plenty of "ideas" of masculinity, lots of my female friends refuse lots of "ideals" of femininity. There's nothing revolutionary about not embracing gender stereotypes. The non-binary movement is around 60 /70 years too late for that! I mean jeez, women in the 50s and 60s were criticised as "not womanly enough" for not wearing skirts!
I already follow lots of nonbinary people. And note that the comments I point to in the article were all made by people who identify as nonbinary. The problem isn't that I haven't listened to what nonbinary people are saying. It's that what nonbinary people are saying is deeply regressive as regards gender stereotypes.
