When there's a form to fill in, if it asks for gender, click none or other, or stress about how there isn't an option and you just have to pick male/female even though you don't HAVE a gender.
... this is what I have been doing with all forms I have to fill out for chats. Because I do not WANT a gender, it is a harmful social construct and I want nothing to do with it,even though patriarchy certainly just loves to force it on me. So, congratulations, according to you I am nonbinary now, or what?
Thankfully, in my native language, there is none of that nonsense, there's only one word, which is for actual, real, biological sex, and the word gender is strictly only used to talk about the harmful stereotypes that feminism aims to abolish.
