"Cis" and "trans" are different types of a person's.... what?

To a first approximation, they describe the match or mismatch between a person's gender identity and their assigned gender at birth (AGAB).

"Cis" = "my gender identity matches my assigned gender at birth"
"Trans" = "my gender identity does not match my assigned gender at birth"

The question being asked is, "Given that when you were born they thought of you as a (boy/girl); are you now expressing or experiencing a (male/female) gender, or a (female/male) one?"

Logically speaking, this is an xor operation; it asks if two things are the same or different. If boolean variable a represents your AGAB and boolean variable b represents your gender identity, then "are you trans?" is a xor b — is your AGAB different from your gender identity?

Again, this is to a first approximation. There are people who don't fit binary labels, and so an xor operation on binary labels doesn't fit them either.

Please note I’m typing this as a trans man. Being “cis” or “trans” stems from someone’s gender.

Basically, do you identify as your birth gender (not sex, gender and sex are different)? If the answer is yes, you are “cis”. If the answer is no, like I my case, I was born female, I identify as a male, then you are are trans.

I hope this answers your question.

Cis and trans are terms that came before their application to gender identity. I learned themin organic chemistry in reference to chemical isomers.

Wikipedia: The prefixes "cis" and "trans" are from Latin: "this side of" and "the other side of", respectively.

As applied to gender, "this side of" you are the gender of the sex you were born as. "The other side of" means you have switched your gender to the other side of the sex from which you were born.

Edit: to answer your question more directly, your gender is cis or trans of the sex you were born as. The question you ask for is: "is your gender cis or trans of your sex?"

I think the confusion is coming from the fact that cis and trans really only have context of an expectation. In this case, it would be the expectation of society.

You are correct that if you identify as a woman or a man, you are a woman or man. If you have a penis, or a vagina, or some mix or lack of those, then those are just parts of your body and that isn't really up to interpretation.

In broad strokes, society expects your body parts (penis, vagina) to correspond to how you identify (man, woman). Humans are kind of just built this way. Our brains take a lot of shortcuts and categorize the world around us. It is statistically likely that if you have a penis, you identify as a man.

As we've evolved as a society, we have come to understand and recognize that these statistically likely correlations not always hold up (it's just likely, not a guarantee, after all). So cis and trans are descriptors of whether or not the correlation between your gender identity and your physical characteristics match (cis) or don't match (trans) society's expectations.

I'm male, I look in the mirror and see a man, I'm fine being a man. I'm gay, I've pondered 'but what if I was a woman'? My body, clothing, etc. ... Nahh, that's not me. I'm cisgendered.

'cis' means, metaphorically, 'same side'. cis- is a prefix used in other disciplines, and was first used in 1914. It's not a 'made up woke word' like bigots claim.

Also, all words are made up. We make language work for us, and it changes all the time. This is a feature not a bug.

Cisgender means the person has a gender identity that matches the sex they were assigned at birth.

If you are a man and you were assigned male at birth, you are cis.

If you are a man and you were assigned female at birth, you are trans.

Non-binary can mean anything from not having a strong specifically male or female identity to closer to switching identities (bi-gender falls closer into this) to just having a lot of serious fluidity, but typically speaking at least part of the time the identity doesn’t match the assigned sex at birth.

I don't think any of you read his question.

They're adjectives. Just like "tall" or "smart" or "young".

The question would just be "are you cis or trans?", there's not a specific word or term that you'd use.

You can think of 'cis' and 'trans' as meaning roughly 'this side' and 'other side'.

In a gender context the 'sides' are male and female and the items are physical gender and mental gender. If both genders are on the same side, both on 'this side', that's 'cis'. If they are different, one 'this side', one 'other side', that's 'trans'.

So, if the answer is "I am cis/trans" the question is "Is your mental gender the same as your physical gender?" "I am cis" then means "My mental gender is the same as my physical gender" and "I am trans" means "My mental gender is not the same as (or maybe 'is opposite') my physical gender".

Note that 'physical gender' is not always clear. Some people are born with ambiguous genitalia and may be surgically altered to make their genitalia more closely resemble the commonly recognized pattern for 'male' or 'female', and some may be left as-is. In some cases this can be a reason for a trans gender identity.

I think it's an alignment, like parallel vs. perpendicular.

If you identify with your sex at birth, whatever it is, your identity is aligned with your biological sex at birth, that is called Cisgender. Parallel.

If your gender identity is not aligned with your biological sex at birth, it is at an angle to it, perhaps perpendicular (you were a boy baby but are a woman) perhaps a different angle (perhaps were born a girl and are non-binary). Anything other than that parallel alignment is thrown into the Trans bucket, but particularly the perpendicular arrangements.

"Describe the relationship between your assigned gender and your gender identity."

Simply, a cis person identifies with the gender they were born with. You were born a man and identify as a man, a cis man. A trans person identifies themself with a gender different than what they were born with. You were born male but identify as female, a trans woman.

If the answer is "I am cis" or "I am trans", what is the question?

The question would, to be blunt, be "are you cis or trans?", because "cis" and "trans" are just shorthand for "cisgender" and "transgender".

It's a question of very limited scope -- even if you were to reword it -- because in modern society, the exact detail of if someone is cis or trans isn't really practically important. If someone is a man, say, society cares a lot more about them being a man rather than being a cisgender man or a transgender man. (I'd say the same about women, but there's obviously a subset of society that is in the process of demonising trans women, so...)

I think the core issue you've found is that cis/trans-ness is something that only makes sense in the context of something else, the gender identity of the person in question.

...Behaviors and lifestyle choices. They do not rise to the immutable characteristics that qualify for civil-rights protection.

And yes; I've seen the sleazy Wiki edit that attaches "perceived" to the definition of "immutable". 'I just have to believe...' belongs in a child's fairytale book.

I agree with what you're stating and I hope that that's where we are headed - there just being man, woman, and non-binary gender identities. For now though, as I see it, cis/trans become relevant in three ways (off the top of my head):

1. Medical situations - self explanatory
2. In pursuance of romantic/sexual relations - society is still at the stage where the visual perception of a person lead to certain presumptions. Not everyone may be okay with dating/having sex with a person who has different genitalia than they presumed that their partner would have.
3. [This point is my personal opinion] The visibility of people openly owning their journey can be a source of information, give courage to others who are undergoing the same journey and are scared or confused. I knew about my orientation way before I realized that there's a term for it or that their are others like me.

I hope I got your query right.
