Genderig isnt an exact science, and more of an educated guess based upon various associations.
This is how we can have such terinology as "girly boys" and "tom boys"
I allways luagth at this, and think how can a boy be GIRLY, and how is a girl a tom BOY. This is the process of gendering, somthing that is not sex but is asociated with either. So these terminology reffer to exspressed behaviours/characteristics.
If we suddendly get a text from an unknown number and it read "I cut myself shaving again last night" we would assume the message came from a male. Because we asociate shaving with men firstly, and with nothing ells in the message to suggest otherwise that is our gender diagnosis.
And the opposit would happen if the message read "waxing is such a pain" This doesnt mean we think only men shave and only women wax, it justs means in the absence of information sugesting otherwise we automatically associat those two things with those two genders.
But gendering doesnt stop at activities, how one sounds and how one speaks are also gendered, aswell as what one wears and how they look in what they wear.
And believe it or not, I myself have been in the situation, whilst sat with a cupple other women, have had somebody say to sombody ells, while pointing directly at me, they used to be a man, and the other person has said "I know, Im not stupid, it obviouse, the're wearing make up, and those shoes dont go with that dress"
I was in jeans and a T-shirt, with knee hight boots. With one day stubble for a laser apoinment later that day. And I never were make up. I also have inherited my dads realy bushy brows and I refuse to spend ages grooming them despite how many people say, you need to do your eyebrows lol.
I also have exsperience with people mis-gendering on the phone to correcting themsleves in person, aswell as a phone pass, becoming a mis-gender in person.
So, what do I exspect?
I exspect people who know me, to gender me correctly, I exspect people working with or for me in a profesional setting to use my legal name and title. (gender not legaly changed yet, so I will make allowences in a profetional setting for the "wrong pronouns") And when this changes I will also exspect the "right pronouns" to be used.
As far as people that dont know me? I as a person make gender asociations all the time, and as a person I am free to get it wrong acationally. I would be a hypocrit to not allow these mistakes in others.
Now when mis-gendering is done on perpose exspecialy in argument with my right to self identify, then I have a problemb, but this is due to a person being hatefull when they dont know me, aswell as the hypocracy of a person who Identifies sugesting I cant Identify.
But this is the behavour of a hater, and haters hate. So I exspect to exsperience that too.
