Definitions and Concepts for trans people

AGAB – Assigned Gender At Birth

AFAB – Assigned Female At Birth

AMAB – Assigned Male At Birth

Cis – you feel like your AGAB

Trans – you do not feel like your AGAB

TERF – An acronym for Trans-Exclusionary Radical Feminist: A social movement focused on excluding trans people from society. They use many methods to gull people onto their side of things with the sole purpose of eradicating any acceptance for trans people in the world.

GENDER – A socio-cultural construct often based on perceived external biological differences but also on social roles within a society, activities, and on unspoken codes and rules: IE Nail polish is only for girls, only boys wear blue (Both of which are patently untrue, men were the first to wear earrings, nail polish, and makeup, high heels, and corsets even, in renaissance Europe. It goes much further back in other cultures. It wasn’t until much later that men let women dress up in all the fancy stuff.)

A June 1918 article from the trade publication Earnshaw’s Infants’ Department said, “The generally accepted rule is pink for the boys, and blue for the girls. The reason is that pink, being a more decided and stronger color, is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl.” Source: Smithsonian

Words like woman, man, girl, boy, et cetera refer to gender. They have nothing to do with genetic sex, perceived biological sex, or what functions our body displays. Our genetic sex and the things our bodies do aren’t relevant to our gender. These are two separate and distinct concepts. Anthropologists and other scientists know this. It’s fact. As many people have said, Our Parts Don’t Determine Our Gender.

SEX – genetic sex on the chromosomal level. Whether someone is xy, xx, xxy, xxxx, xyy etc. and how that affects what our bodies can/can’t do. A person can look and feel like a cis male and be xxy. A person can also be a “woman” to everyone’s perception and be xyy. (Not even sex is binary, sorry nonscientists, it just isn’t, 7th-grade biology lied to you. Shocking, I know.) This is the only way in which ‘sex’ matters to anyone, and the only one it matters to is the person who is carrying those genetics, their medical team, and if they have them, their partners. For further reading on this subject here are a couple of twitter threads that make it easy to understand.


So. Hi new people! Apparently, we’re gonna talk about sex. Like physical sex! Because… there’s some confusion.

First, sex defined: We’re talking physical sex here, not gender. Body parts, hormones, and genetics (and more).

BLUF: BIOLOGICAL sex is a spectrum

This tweet went viral over the weekend, and I got a flood of questions about sex, gender, and genetics. I wanted to wait until after Christmas to delve into addressing them. So let’s go.

As a geneticist, I must say this is incorrect. Those chromosomes don’t determine gender. And there are more than those two karyotypes (chromosome combinations) in humans. And don’t get me started on other species.

GENDER IDENTITY – What one feels inside, their own internal perception of their gender. MANY cultures from all over the world throughout recorded time have always known there’s a distinct difference between gender and perceived biological sex. Scientists in pretty much all fields know it today. It’s only in modern society that people like Rowling have their heads up their rectums about it.

PERCEIVED BIOLOGICAL SEX – What someone looks like to someone else. This is fraught territory because there are butch cis women who look masculine and there are femme looking cis men. The point being, of course, that you cannot tell what someones’ gender or genetic sex is by looking at them. It’s actually impossible.

Utterly impossible, you’d need a compound microscope to see genetic sex/chromosomal sex and I haven’t seen many of those in girls’ bathrooms or boys for that matter. As far as seeing into someone to try to figure out what their gender is? I don’t think we’ve developed telepathy and thought sensing yet, have we? So why don’t we just do the radical thing of believing people are who they say they are with regards to gender? Hmm? Peachy.
