Am I easily confused or is this a confusing article?

Here is an article about the Facebook thing:
www.telegraph.co.uk/technology/facebook/10930654/Facebooks-71-gender-options-come-to-UK-users.html

So what I’m understanding is that gender and/or non binary means whatever the person discussing it means even though someone else would say it was something else, they’re both right because it’s what they think?
Well, the principle here is that gender identity is a highly individual, personally felt thing. There is really no way of questioning anyone else's gender in this theory, because it's how a person feels/identifies.
When someone says they are non-binary, it basically just means they do not identify with their biological sex (or the stereotypes that come with that sex, such as acting in a "feminine" manner). But they don't identify as a member of the opposite sex, either. They're somewhere in the middle, or something else all together. And people really vary within the non-binary category as well.
I cannot answer the question as to why some non-binary individuals don't just use the single-sex facilities that are designed for their physical bodies... I suspect it is because they do not want to be associated with their actual sex, and see the little woman on the door as "invalidating their identity, and oppressive." Some non-binary individuals tend to push for gender-neutral (unisex) options. Some non-binary people might actually be fine with using the ladies'.
Basically, YANBU.
This is very confusing.
It comes from a philosophy called Queer Theory (I think), but I can't actually get into it as I find it completely unreadable and nonsensical.

ME, ME, ME, ME, ME, I'm special I am!

I so want to go about my business quietly without drawing attention to biological sex, which I reject as a non-binary person. So I'll plaster my face and name all over the internet advertising the fact that I menstruate, that'll help my gender dysphoria that will....

I have no further words to add .....

I think the way it works is that Enby (NB) is a gender identity inasmuch as not identifying as a gender is an identity.

Christ, that sentence made my brain hurt. Genuine question: where the fuck has all this nonsense come from? (I don't mean genuine gender dysphoria). I'm new to all this and trying to get my head round it.

It was very confusing. If you don't identify as male or female, why do you need to be in the men's loos?

AAIK, in current trans theory non-binary is its very own gender identity, just like your conception of whether you're a man or woman. There are many many arguments on YouTube about "how many genders" there are. I believe that non-binary is also an umbrella term, wherein you can describe your gender identity in whichever way is most right for you, and it can change (gender-fluid). This is why Facebook has something like 70+ gender identities. Theoretically, there could be an infinite number of different possible ways to describe gender identity because people are confusing personality with some quasi-biological notion of gender which are all seen as equally valid.

Is non binary a gender?

Now, to many of us, this would seem like the sort of "Paradox, a Paradox, a most amusing paradox" of the sort immortalised by Gilbert & Sullivan.

However, others would say non-binary:
is/not a gender (identity);
does/not mandate 'they' etc. as pronouns;
can identify as non-binary women/men (similarly to Edward Lord) etc.

There is no clarity but it's not an area where clarity is deemed necessary (it might even be deemed oppressive as in examples where non-binary people complain about the use of pronouns that are coded to their appearance) until it suits somebody's agenda.

Don't most people put that level of self consciousness behind them in their early twenties unless it is a symptom of a mental illness?
I know people who feel they are being watched and judged constantly but they are aware that it is them and their imaginaries that are the problem, not other people.

All that I want is to be able to walk into a store and buy tampons free of judgment

Oh what piffle. They can- we all can. Those of us living in any country where sanitary products are openly on sale can all do this.

We can fling them in the trolley with the weekly shop; we can send husbands, boyfriends, even teenage sons down to the corner shop or the all night garage shop to buy them and not one, single, solitary shop worker raises an eyebrow, bats an eyelid or cares a single, solitary fig.

I agree with AncientLights, OP.

It's inventing a problem, to which they have no solution. Exhausting.

Woman has period accident, uncomfortable dealing with in the men's room.

Shock.

It's not you. So many possible solutions if this were a genuine regular difficulty for Cass rather than a talking-point for self-promotion and self-apotheosis as a leading light in pomo thinking.

I can't open the link, OP, but they sound like the usual deluded, narcissistic, self-obsessed twits who spout that crap. Attention seekers. Ignore.
