"the Equality Network defined transgender as ‘people who find their gender identity or gender expression differs from the gender they were assigned at birth"
Quick Google for gender expression gets me this from Wikipedia:
"Gender expression is a person's behavior, mannerisms, interests, and appearance that are associated with gender in a particular cultural context, specifically with the categories of femininity or masculinity."
On any given day I am extremely unlikely to be wearing any item of clothing sold as being for women apart from my bra (which is an unfortunate necessity). I prefer men's shoes because they're wider and flatter, men's socks because they're less restricting and come in better colours, men's trousers and jeans because I have narrow hips, men's briefs because I find the fabric, seams and cut more comfortable, men's t-shirts because I don't like the fitted feel of women's shirts, a men's hoodie for the same reason, men's coats because they're thicker and better quality for the same price with pockets that are actually pockets, and if I wear a hat it'll be a men's hat because I have a massive head. I don't wear makeup because I don't like the way it feels and looks on me and can't be bothered. Except in lockdown, I have a short back and sides because it's easier to care for. I don't sit with my legs together because I see no point in permanently tensing my thigh muscles for the sake of random people's opinions. I like technology. By my local cultural standards my "gender expression" is overall probably masculine. My "gender assigned at birth" would, presumably, be the one associated with my female sex.
So by the definition above — AFAB, masculine gender expression — I'm trans, whether I like it or not.
Fuck off.
